@Captain24 yeah give it a go!! And if frustration does kick in because it is taking ages for any kind of change to happen, do try to remind yourself that you're undoing neural wiring that has taken years to develop. It will take time. I honestly think sometimes one of THE most frustrating things about recovery is that it goes so slow and isn't always noticible! But if you keep taking those steps you will eventually be miles away from where you were.
Are you and your psych working on ways to expand your window of tolerance? I think that's usually the approach right? It's funny I just went to go look it up and I found this that spoke about how things are often easier for us to tolerate if we are the ones choosing them. I think it makes sense, autonomy is so important for a sense of safety! So that might even be a contributing factor - if you're always stuck in fight/flight/etc then the idea of being told you need to do this or that in order to 'feel better' would definitely create inner turmoil!
I also wonder how much of a role shame plays in this conundrum for you - like, when the activity you're doing doesn't make you feel better, even though it's apparently supposed to, does it bring up feelings of failure and ineptitude? Because again, that's going to end up creating a lot of inner conflict. You can always just gently remind yourself that you're working through many years of whacky brain wiring, and just blame the neurons!! Stupid neurons.
Even if it is a kit, you're still engaging in play! And we know how important play is. Maybe that's another thought (sorry I know I've been piling a lot of them on you tonight!), to try to find self-care activities that feel like play instead of a chore or 'something for someone else' i.e. your therapist.
When was the last time you did something silly, whimsical, or spontaneously cheeky?
