I can't claim to fully understand the things that you've gone through, but I've been dealing with my own past and have noticed a few things about my thought processes.
Fisrstly, for me at least, it's easy to fall into the trap of thinking that "nobody cares". That's probably because of social media focusing on the negative or me looking for things to be upset about. It's not really true through; a lot of people have been through horrible things and there's a lot of advocates out there campaigning for rights and protections. Ultimately, I'm not alone, even though that's how it feels some times.
Possibly related to the above, I also have been putting pressure on myself to "fix" these issues. Often to the point where I'm "not allowed to be happy" because there's so much suffering in the world. But I saw a post where someone brought up that being an advocate is a full time job with training and a required skillset. I don't think it's fair for me to put those kinds of expectations on myself, especially with my own mental health issues. I'm trying to adopt a mindset of doing what I can, where I can and not stressing about "not doing enough".
Anyway, rambling over. Not sure if my experiences are helpful, but there you go. :P
If I may give some generic unsolicited advice: Take care of yourself; give yourself space and time to heal. Don't put too much pressure on yourself to move forward quickly. Take care of your physical needs (sleep, hydration, exercise, diet). And good luck.
