Thanks to everyone's help. I'm going to tell my parents on Monday. I'll probably miss Thanksgiving though... And, yeah, those people were me. I just wanted answers I guess to convince myself that I did need help, and I got that, so thank you.
As for my brother, when I was hospitalized two weeks ago I told them about him and I almost got taken away from my parents and my brother, but we put alarms on the doors and everything, and it's all fine now. He still lives with me, but doesn't molest me anymore.
Anyways, thanks again!
