What we do together
It is not "will not". It is "cannot", and that difference changes everything.
The starting point is that the avoidance is not a choice. It is a nervous-system alarm set off by the loss of autonomy, hormones in the body and all, and once it is lit it does not resolve through willpower. That is why rewards and consequences have never worked on you: they address a decision, and there is no decision here.
So we do not work on making you more compliant. We work on three things. The anxiety underneath, because that is the engine. Recognising the demands, including the hidden ones, the implied ones and the ones you place on yourself, which are usually the hardest. And finding the shape in which a necessary thing can be done without going through the alarm: with choice, with options, with wording that does not land like an order, with renegotiation and no shame in it.
How I work is as important here as what we work on. I do not set you homework. I do not fix objectives for you to sign off. I do not press subjects you steer around, because pressing is itself a demand. You can move the time, you can cancel, you can say halfway through a session that you do not want to talk about this, and none of that goes down as resistance. A plan you make is your demand; one I hand you is mine, and that is the kind that locks up.
What I draw on: polyvagal work, for the alarm in the body. Internal Family Systems, for the part that guards your autonomy, which is not an enemy but a guard that had its reasons. Schema Therapy, for what formed in the years you were called difficult. And Person-Centred practice, which here is not a matter of style but a condition of the thing working at all.
