AITAH for hating my brother?
I, F 17 have a brother, M 13 who is severely autistic and has adhd. I hate his guts and idk if I should feel bad about it. My parents have been divorced for over 12 years now and my brother lives with my dad and I live with my mom. On the weekends I'm at my dad's house sometimes but my brother is also there and I hate it to be here when he's here. He irritates me to my core. He follows me around and calls me things like 'slut' or 'bitch' my dad punishes him for it but nothing happens, my mom punishes him too but because he's autistic and ill she doesn't want to punish him as much as my dad (he has a illness called NF1, you can look it up) he also is very very sexual and downgrading towards woman and I just hate him. He literally jerks off to my underwear and it's disgusting, the first time my dad even hit him (idc what yall think about that we're raised old school) I just CANNOT stand to be around him and I just hate him. If I could I don't want to see him anymore but I can't. He fucked up so had that my boyfriend doesn't want to come over anymore. I also don't like the way he is towards my mom, he never visits or calls and he ignores her for long periods of time. My dad doesn't do anything about it because he hates my mom and he thinks my brother is old enough to choose where he wants to be and I just hate it. I hate him and everything he does. I'm sorry if this is more of a rant than an actual advise thing but I don't have anybody to tell this to. My family is just really fucked up and I hate it.
I'm sorry if there are spelling mistakes, english isn't my first language!!
I hope someone can give me advise or anything, just something.
