As an autistic/ADHD veteran of therapy, trauma and MH issues, I think you might be better off looking for therapy that focuses on coping mechanisms generally - obviously with someone who has genuine knowledge/experience of neurodiversity.
This is as opposed to a therapist who is there to listen to each situation as it arises. I’m not sure the latter approach is actually so helpful long term, even though it feels like it at the time.
The problem is if you’re in such a fucking awful situation (and I’m very sorry you are - best of luck with the surgery 💐) it’s not something that can be changed and in future when something happens you’ll feel lost again if you don’t have that instant support.
I found an ex NHS psychologist who now works as a therapist. Her NHS work was largely with autistic adults. The first few sessions, other than telling her the basics of my past and current circumstances, actually ended up being focused on learning how to cope with therapy sessions - very meta 🤔🤣.
Recently I’ve realised how well the therapy has worked because it’s got to the point where I can face difficult situations and apply the techniques she’s taught me. I’ve had sessions where I thought I’d be talking about some really difficult situations, but by the time I have the session I don’t need to other than the basics, because holy shit, I have actually learned to cope SO much better. Never ever thought that would happen.
I don’t know, I just wonder if that may be a better approach for you. It’s not invalidating the fact you have a really tough life with lots of responsibility, not at all, but it sounds like the sort of “talking stuff through as it happens” therapy may not be right for you. 💐
