@BrentfordForever Quatiapine is a commonly used drug for bipolar - but it doesn't really sound like OP shows much sign of bipolar, and it'd be a slog to get a diagnosis for that if one has been actively withdrawn.
@Hamandcrispsandwich I am really sorry you feel like this. For what it's worth, I saw a lot of therapists in my early 20s, and had the same situation... they'd push me to talk about my family, and my parents, and then I'd inevitably be moved to a new therapist, and the same would happen again. On three separate occasions, the therapist had to take time out while I was talking. In one of those, she threw up, in another, she left the room and what felt like a lifetime later, the receptionist came in and said she was unable to finish the session and someone else would be in touch with me. They never were.
I was absolutely lost in my tiny world. My ED went the other day and I hoarded food and ate too much, because it gave me the tiny slithers of happiness, and I felt in control of choosing what to eat, at least...
I'm in my mid 30s now. I have two children, a husband, friends. I still have anxiety sometimes and raging RSD, but for the most part, I'm unrecognisable from before. I can't say I've hugely processed the family stuff... but before I had the children, I'd moved past it enough that it almost felt it happened to "another" me. I'm not sure how healthy that is; but it's how it is! Nobody could cope with hearing the details to help me, and nobody felt they could help without hearing the details, so it felt like the only way forward was to not need to process it.
I'm not sure the specific ways I did it will help you. I had to give up my remote job and force myself into an office. Then days out... I started going out at 10 (because it's quieter then!) and making myself stay out until 12, then 2, then 4, then the whole day. It was mentally exhausting to start with but it expanded my world ten-fold, and it gave more opportunities for tiny positive interactions with people like baristas. Ironically I work remotely again now because it works better with my life, but the office stint did me a lot of good.
Throwing myself into causes helped - learning about things, volunteering, things that are very much not about me. I learned to train guide dogs. I started by washing them and supervising them playing, and then became a trainer. They offered me a job at the end - I didn't take it, but it was validating, and it was time that my brain couldn't turn over what I'd been told. By the end, it was time that directly contradicted what my brain said. How could I be useless if I was training dogs? If I was doing good?
It was a long slog, I don't want to pretend it wasn't, but I'm so far through the other side now, and it's so worth it. I can barely remember the days I spent locked in my bedroom in a rented house because my world was so, so small.
I would also explore autism. Support for that could be life-changing for you, if it applies, and I've heard that Quatiapine can sometimes temporarily assist with symptoms - it's a form of masking, I think, but I saw that it'd sometimes been effective for 12/18 months and that's something you could explore, alongside help for what you're struggling with now. In my experience, there may not be a way to process everything that happened, but you can absolutely change your own outlook. Brains are immensely powerful but you can control yours, you can.
It's valid to just feel the pain for a bit too, though.
I hope you're doing okay today. Remember that each meal is a step towards freedom from this, in whatever guise that takes for you.
