My Stuff, Your Stuff

On emotional boundaries, enmeshment, and the ancient call to love your neighbour as yourself

There's a moment that most of us in close relationships know well. It's the moment when you can't quite tell anymore where you end and the other person begins. When their bad day has become your bad day, without anyone agreeing to that arrangement. When you're carrying anxiety that isn't really yours, or guilt for something you didn't do, or responsibility for someone else's emotional experience that was never yours to manage.

It's disorienting. And it's exhausting. And it happens constantly, in families, in friendships, in marriages, and in workplaces because human beings are, at a neurological level, built to absorb one another.

This post is about that. About what we carry into relationships, how it collides with what others carry, and how the line between my stuff and your stuff gets so blurred. We'll look at what psychology and neuroscience tell us, and then we'll sit with what the Word says about the kind of selfhood that makes genuine love possible.

We Are Wired to Absorb Each Other

Let's start with the science, because it's really interesting. In the early 1990s, neurophysiologist Giacomo Rizzolatti discovered what we now call mirror neurons: brain cells that fire both when we perform an action and when we watch someone else perform the same action. The brain, in a very real sense, rehearses other people's experiences inside itself.

This is thought to be the neurological foundation of empathy. We don't just intellectually understand what someone else is feeling. We simulate it. We feel a version of it in our own bodies.

Daniel Siegel takes this further with his concept of co-regulation, the idea that human nervous systems are not self-contained but are designed to regulate one another. A calm presence can soothe a dysregulated nervous system. An anxious one can ramp another up. This isn't a metaphor. It's measurable physiology.

The implications for relationships are huge. It means that emotional contagion, catching someone else's mood or state, is not a weakness. It's not you being too sensitive. It's your nervous system working exactly as designed. The question is not whether you'll absorb others. You will. The question is whether you have enough internal grounding to know when it's happening and to come back to yourself.

What We Bring to the Room

But before we even get to what we pick up from others, there's the question of what we already arrive carrying.

Nobody enters a relationship without history. We bring our attachment patterns, the internal blueprints shaped in childhood, for how we relate to closeness, need, conflict, and intimacy. John Bowlby's insight was that these early relational experiences don't just shape our childhoods; they become the operating system for all future connections.

The anxiously attached adult carries a nervous system that is perpetually alert for signs of rejection. They may interpret a partner's quiet mood as withdrawal, a friend's slow reply as disinterest, a moment of distance as abandonment. This is not irrational. It's learned. Their early experience taught them that closeness was unpredictable, that they had to work to hold people, that safety was never quite secure.

The avoidantly attached adult may carry the opposite: a learned belief that depending on others is dangerous, that showing need brings punishment or contempt, that emotional distance is protection. So when intimacy deepens, something in them pulls back, not out of cruelty, but out of self-preservation that was once necessary and is now automatic.

These patterns are our 'stuff.' And the painful reality is that most of us don't know we're carrying them. They feel like the truth. They feel like other people are just untrustworthy, smothering, or leaving. It takes real work, often therapeutic work, to see the pattern clearly enough to question it.

Projection: Seeing Your Stuff in Someone Else

Carl Jung described the 'shadow': the unconscious, unacknowledged parts of self that we can't quite face. The parts we've pushed down because they were unacceptable to us, our families, or our communities. These might be capacities for anger, for selfishness, for desire, for vulnerability, anything that got labelled as too much or not allowed.

Here is Jung's observation: we don't make the shadow disappear by suppressing it. We project it. We see it in other people. We react to it in them, often with an intensity that isn't justified by the event, experience or interaction, precisely because we can't see it in ourselves.

This is one of the reasons strong emotional reactions to others are worth paying attention to. Not every strong reaction is projection. But when the intensity seems out of proportion to what actually happened, when someone's behaviour bothers you far more than seems reasonable; it's worth asking: Is there something here that resonates with something in me?

Projection works the other way too: we can project our own goodness onto others, assuming everyone is as trustworthy or well-intentioned as we are. Or we can project our fears and see threats where there are none. In close relationships, untangling what's projection and what's accurate perception is some of the hardest and most important work there is.

Enmeshment: When the Walls Come Down Completely

Murray Bowen, one of the pioneers of family therapy, introduced the concept of differentiation of self: the capacity to remain emotionally connected to others while maintaining a clear and stable sense of your own identity, values, and inner life. High differentiation doesn't mean coldness. It means you can love deeply and still know who you are. You can be moved by someone's pain without being consumed by it.

The opposite, what Bowen called fusion, and what is more commonly referred to now as enmeshment, is when that distinction collapses. When your emotional state is entirely dependent on someone else's. When you can't be okay if they're not okay. When their choices feel like they're happening to you. When saying no to them feels like betrayal, and having a different opinion feels like an attack.

Enmeshment usually has its roots in the family of origin. Children who were used as emotional support by overwhelmed or struggling parents, or who lived in a family system where there was no clear emotional boundary between individuals, often grow up with a deeply wired sense that love means merger, that to be close is to dissolve.

This shows up in adult relationships in patterns that are recognisable but hard to name while you're inside them. The partner who cannot cope with any disagreement. The friend you can never say no to without days of guilt. The family member whose mood sets the tone for everyone in the room. The version of yourself that loses track of what you actually think or feel because you're so busy managing what everyone else thinks and feels.

Genuine intimacy requires two distinct selves. Enmeshment, though it can feel like closeness, is actually its counterfeit because there is no real meeting between two separate people. There is only merger.

The Biblical Vision of the Self

"Love your neighbour as yourself." Mark 12:31

This command is so familiar that we can miss what's embedded in it. Jesus doesn't say love your neighbour instead of yourself, or more than yourself. He anchors neighbourly love in self-love, as if the two are proportional. As if you can only genuinely love another person to the degree that you have a stable, honest relationship with your own inner life.

This is not selfishness. This is the theological foundation for differentiation. You need a self to give. You need to know what you carry, what is yours, and what belongs to someone else, in order to love wisely and sustainably. The person who has collapsed into everyone else's needs, who has no 'self' left to bring, is not loving generously. They are disappearing. And that is not good for anyone.

"For we are God's handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do." Ephesians 2:10

The Greek word translated 'handiwork' here is poiema, from which we get the word 'poem.' You are not a mass-produced product. You are a crafted work, unique, intentional, specific. The Bible speaks to the uniqueness of each person. You are not interchangeable with others. You are not simply an extension of your family system or your community. You are a distinct self, called, named and known.

This theological picture of personhood is actually a strong argument against enmeshment. If every person is a unique image-bearer, then losing oneself or one's personhood to another is not devotion; it's a loss of something God intentionally made. Healthy love, in this framework, honours the distinct personhood of both parties.

"Each one should carry their own load." Galatians 6:5

This creates a slight tension with verse 2 of the same chapter: 'Carry each other's burdens.' But the Greek words are different. In verse 2, 'burdens' refers to crushing weights, things we genuinely cannot carry alone. In verse 5, 'load' refers to the ordinary weight each person is responsible for carrying themselves. There is a distinction between coming alongside someone in crisis and taking on what is theirs to carry.

The pattern of taking on what belongs to others, rescuing rather than supporting, managing instead of accompanying, is not faithfulness. It can be a form of control dressed up as care. And it often comes from our own stuff: our own anxiety, our own need to be needed, our own discomfort with others' pain.

"Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is, His good, pleasing and perfect will." Romans 12:2

The renewing of the mind that Paul describes here is not simply about theological information. It includes the slow process of having our defaults and patterns examined and reordered. The automatic responses: the projections, the enmeshed habits, the reactive patterns, are the 'patterns of this world' that have formed us. Transformation involves becoming aware of them. That is painful, slow work. It often requires relationship, community, and for many people, professional support.

In Biblical tradition, self-knowledge is inseparable from the knowledge of God. Augustine's famous prayer, 'Lord, let me know myself, let me know you', treats the two as linked. You cannot love well what you cannot see clearly. And you cannot see others clearly if you cannot see yourself.

What Mentalisation Offers and What Faith Adds

Peter Fonagy's concept of mentalisation, the capacity to understand your own and others' behaviour through the lens of inner states, is one of the most practically useful ideas in relational psychology. When we mentalise well, we can slow down in the middle of a charged interaction and hold the question: What is happening in me right now? And what might be going on for them?

This takes practice. It's hard to do when the amygdala has fired and rational thought is offline. But it can be developed, in therapy, in safe relationships, in any environment that creates enough safety to be curious rather than reactive.

What faith adds to this is something that psychology alone cannot provide: a theological framework for why it matters and a relational source of security that holds the process together.

The concept of being known by God, fully and without defence, offers something that no human relationship can fully provide. 'You have searched me, Lord, and you know me,' it says in the Psalms. 'You know when I sit and when I rise; you perceive my thoughts from afar.' (Psalm 139:1–2)

There is something very stabilising about the idea of being fully known and not abandoned. For people whose early attachment was shaped by the fear of being truly seen, this is not a small thing. It is, potentially, the very safety that makes self-reflection possible.

The spiritual practice of examination, of sitting honestly with your own inner life before God, is a form of mentalisation. It asks, "What am I carrying?What is mine and what is not mine? Where am I reacting from old history rather than present reality?" These are not just therapeutic questions. They are the questions of a soul trying to love well.

So What Do We Actually Do?

Start with curiosity, not judgment. When you notice a strong emotional reaction, especially one that seems bigger than the situation warrants, get curious. What's happening in me? Is this about now, or about then?

Learn to come back to yourself. When you've absorbed someone else's state, and you will, practice noticing it and returning to your own ground. What do I actually feel? What do I actually think? What do I need?

Revisit your history. Attachment patterns, projection, enmeshment, these all have roots. You don't have to dig it all out at once. But a willingness to look at where your patterns come from is the beginning of not being run by them.

Get support. For many people, this is work that genuinely benefits from a skilled therapist. Not as a luxury but as the kind of honest, guided relationship where these patterns can be seen clearly and slowly rewired.

Hold it spiritually. If you are someone who believes, bring your relational patterns into your prayer life. Not as shame but as offering. 'Lord, here is what I carry. Here is where I get lost in others. Here is where I cannot tell my stuff from theirs. Come and help me know myself.'

And extend grace, to others and to yourself. The work of telling our stuff from someone else's is genuinely hard. None of us gets it right consistently. The goal isn't perfect emotional hygiene. The goal is more awareness, more honesty, and a little more love, for ourselves and for the complicated, beloved, stuff-carrying people in our lives.

Be blessed today in the mighty name of Yeshua!
