I'm sorry you're struggling. I've been in your shoes, not able to work full time, self-isolating, and having problems in relationships.
I too have a history of trauma, and what turned things around for me was getting real, good, trauma therapy. With trauma therapy I feel like I've made more progress in the past 3 years than I had in the preceding 20 of talk therapy.
The trauma therapy was brutally intense, but since doing it, I've been able to up my hours at work from 12/week to 32/week which is just short of full time, I genuinely like myself and my life, and I've started dating which felt impossible before. If you'd asked me 5 years ago if these things would be possible, I would have said not a chance.
I hope you too can find a solution that works for you.
