Is OTHER wrong in the post ? POST : I'm 20 and I live with my parents, so I commute to college. It takes up to 4 hours everyday and it's so exhausting. But now.. A little backstory..

My parents have abused me, both physically and emotionally, up to this day. The physical abuse stopped around 2 years ago, but the emotional abuse is ongoing. I've ran away from home and moved out before, but my family were successful at manipulating me into thinking that they love me and that I'll be having a good life with them and thus made me move back home (very bad decision). Due to the ongoing abuse I got diagnosed with ptsd and have other mental issues. Even my counsellor advises me to move out and start fresh, but my family thinks it's a bad idea and get very angry at me for wanting to grow as a person. I  tell them that I wanna be happy but they're saying that I'm just ruining things for them and that I should stop being selfish.

Now the issue here is: I told my parents about moving out and they got mad at me for being selfish and wanting something like that when they do so much for me. And that everyone gets tired and I'm not special and sometimes humans just have to accept their fate. 

They say that I'm egotistical and horrible for wanting to move out since one of my 4 siblings has an illness and might get surgery for his knee and they need to focus on him and that I should help them and not take much space. 

Moving out will be the start of my recovery and I really need this.. At 20, I'm still suffering for things that my parents put me through.

So.. AITA for wanting happiness for myself at the cost of not helping them out?
