Why Do I Keep Reacting the Same Way When I’ve Understood It for Years?

You know that comment probably wasn’t an attack.

You know that disagreement doesn’t mean the relationship is in danger.

You know you are allowed to rest, say no, and take up space.

You may even know exactly where some of your reactions come from.

And still, something inside you keeps reacting.

Your body tenses. You withdraw. You anticipate what might happen and try to control everything. Suddenly, you feel small, unsafe, rejected, or responsible for doing whatever it takes to make things calm again.

Then often comes a second reaction:

But I know all this. I’ve understood it for years. Why is it still happening?

This gap is exactly where parts work can become useful.

Understanding your story is not always enough to transform it

You may know that a fear began in childhood, understand why you constantly seek approval, or have identified the roots of your hypervigilance.

That understanding matters. But it does not always change what happens automatically inside you.

A difficult experience does not leave behind only a story you can tell. It can also leave tension in the body and an implicit expectation:

It’s going to happen again. I need to be careful. I can only rely on myself.

You can know perfectly well that the danger is over while one part of you continues to behave as though it were still happening.

This is an important difference between understanding a traumatic experience and transforming the way it continues to live inside you.

The reactions that trouble you today often have a logic

A reaction does not necessarily appear because something is “wrong”.

Very often, it learned a job.

Staying constantly alert may have helped you notice changes in the atmosphere early. Pleasing people may have reduced conflict. Asking for nothing may have protected you from disappointment. Analysing everything may have created a sense of control when very little was actually under your control.

These strategies may have been intelligent, even necessary.

The difficulty is that they can continue long after the circumstances have changed.

One part of you knows that you are here, today.

Another is still protecting a much older reality.

What is parts work?

The starting point is simple: we do not always react as one single, unified whole.

One part wants to speak. Another says: stay quiet.

One part wants closeness. Another says: don’t trust anyone.

One part is exhausted. Another replies: you’re not allowed to slow down.

These are not separate personalities, but different ways of protecting within the same person.

In an approach informed by Internal Family Systems (IFS), these reactions are not treated as enemies to eliminate, but as parts that took on a role for a reason.

So the question is not: How do I make this reaction disappear?

but: What is it protecting? What is it afraid of? What does it still believe it needs to prevent today?

What can a session actually look like?

The work does not necessarily involve telling the story of your past.

Often, we begin by slowing down and gently turning attention inward.

You might notice a sensation in your body, an image, a memory, or simply the feeling that “something” is there.

We are not searching for the “right” memory, and we do not decide in advance what should appear.

We follow what comes.

And we always move at the pace of what you are able to stay with. At any point, we can slow down, stop, or return our attention to the present.

Sometimes a part appears quite clearly: young, suspicious, angry, exhausted.

Instead of analysing it from the outside, we gradually begin to relate to it.

And the work can become surprisingly vivid.

Take a fictional example. Anna knows very well why she rereads an email ten times before sending it: she grew up in a home where the atmosphere could change from one moment to the next.

She has understood this for years.

It changes nothing.

In a session, instead of talking about it again, we pause with what happens when she imagines pressing “send”: pressure in her chest.

As she stays with it, an image appears: a little girl listening for the sound of keys in the front door.

The part that rereads the emails is not “anxious for no reason”.

Thirty years later, it is still doing the little girl’s job.

When a part no longer has to carry alone what it has been carrying

Some protective parts are still living inside an old experience that, for them, never really ended.

They may be protecting a younger part that remains caught in an earlier fear, shame or loneliness.

When that part can finally be met differently — accompanied, believed, protected, allowed to leave that old scene, to say no, or no longer carry everything alone — something can change.

The memory does not disappear.

But the way the experience is carried today can transform.

We move from: I know why I am like this.

towards something more like: I can meet the part of me that is still living in that reality.

The body is often part of the way in

Parts do not always appear through words.

They may show up as pressure in the chest, a knot in the stomach, tightness in the throat, agitation or an immediate urge to leave.

That is why I also pay attention to the body in this work.

Somatic and trauma-informed approaches can help us stay with what is happening without forcing the system or going beyond what feels manageable.

EMDR-informed tools can also be useful when an earlier experience is strongly reactivated in the present.

But the methods are not the centre of the work. They are ways of meeting what is already there.

You can explore the different ways we can work together, from a single session to a four- or eight-session pathway.

The goal is not to fix you

There is no defective version of you that needs to be corrected.

The work is about helping your parts discover that they may no longer need to hold the same position, alone and with the same intensity.

A vigilant part can keep its sensitivity without monitoring every second.

An independent part can keep its strength without refusing all support.

A perfectionistic part can keep its standards without turning every mistake into danger.

Change does not come from making these parts disappear, but from transforming the way the traumatic experience continues to be carried in the present.

Where do you begin?

If you recognise yourself in this, the part of you that is still carrying the experience may simply never have been met where it actually is.

And that is often where the work begins.

I work online with adults in English, French and Danish, using parts work informed by IFS alongside somatic and trauma-informed approaches.
