I'm so sorry for you. You've gone through so much.
The fact that they could love someone who acts without love, yet shun someone like you who is just trying to live the life they deserve... disgusting.
You deserve to be around people who can accept you and nourish your life, not kill you with their selfishness. You deserve love.
Personally, I'd say its not just non-acceptance that leads to LGBT+ suicide, but misunderstanding. I'm lucky enough to have a supportive family, but when i "came out" as a lesbian to the accepting side of my family it was still a big deal to them. One of my sisters was excited that I was gay, and she was like "I always kinda knew, there were signs". You'd think that's a good thing, but think about it. I've never been in a relationship, and I'm not trying to form one. In a perfect world, whether I'm gay or not shouldn't affect anything about my life or how people perceive me, and yet, it does. This small detail completely changes how people view me, and because of that, I can never separate me personality from my identity as a lesbian.
To make things more complicated, I've only recently began to realize that I don't really want to identify as a woman. I'd rather identify as nonbinary. Yet, like you, I'm a feminine lesbian. I like dresses and makeup and shit. But to other people, what I appear as (a girl) is always going to be what they think of me as. Even if I were to come out about this to my family, I know they would support me, they would accept me, but they would never understand me, because society has clouded their perception on what it means to be LGBT+ and twisted it into something i can't untangle.
Sorry to vent, I just got kind of passionate. This thread is about you. But, that's my opinion. I think misunderstanding also plays a big part.
