That sounds like more trauma than anyone should ever have to bear :( I’m so sorry that people have been so terrible.
As you can probably tell from my post, I’m just a baby — I only came out publicly a few months before lockdown in 2020, and so I’m still very much sorting through things myself. I only get whispers of how toxic some LGB spaces can be to trans people. (Although I have had too much experience with trans people being toxic to each other).
I hope you can find some peace. You deserve that and much more.
