I had a therapist that eventually deemed me too dangerous to myself to be in their care, so she upgraded me to super-therapy where I have to go like 9 hours a week and work with a group and like 5 therapists but I still don't get much value out of it :c so yeah, therapy definitely isn't for everyone
Yeah it's one of the most challenging parts. The process of getting therapy is not set up to be easy for the kind of people who need it. Availability is the most limiting factor these days, so if you don't get a good match, you could be stuck waiting months for another try. I got pretty lucky on my second try a few years ago, but my wife just gave up trying to find someone. It's hard to blame her.
