Basically had a mental breakdown last night

I'm 16, and I've been struggling with terrible anxiety and depression for a while now but it's gotten really bad this past year. I've had so much bs happen to me and last night I felt terrible about all of it.

My dad is a *** that verbally abuses me regularly and has threatened multiple times to hurt me. I got SA'd when I was 8 years old and I think about it almost daily and it weighs on me so much. I've had problems eating recently and I've basically become anorexic. I'm a closeted bisexual in a really homophobic home and I come home every day to my dad complaining about the "f*gs in this country", not knowing I'm one of the "f*gs" he's talking about. I was rejected last week by a girl I was talking to for a whole month and then I saw her walking around yesterday holding a bouquet of flowers. I have a weird phobia of sleeping because of a nightmare I had a few months ago involving my dad. I have more problems going on too but for the sake of not typing this for too long I'll skip it.

I was sitting in my bed last night feeling guilty because I ate more than I wanted to and I was scared I'd get fat. I started thinking about all the other *** that's happened to me and I genuinely think this is the lowest I've felt in a long time. I started hyperventilating, crying, and shaking in my bed and I just felt like ***. I just wish that I didn't have to go through this bs.
