My sister is the reason I wanna commit suicide but I'm not going to do it...?

She's just very toxic. I can't explain everything here but she gives me anxiety, I hate being home. I sleep most of the time when she's home. I hate being around her because she brings up certain things that she WANTS me to ask about when I don't care. She loves attention and I hate that about her. It's annoying and kinda stressful. I know my sister does have some sort of "big ego" problem but she doesn't want help or she refuses it or whatever. I never asked but that's just the way it seems. She gets angry at me and avoids me when I lose weight or get paid more than her. I don't know why?? I just do things to make me happy and she for some reason hates that. I try to avoid her but I do love my sister and we do have some good times but at the same time she is the reason I want to end my own life. I'm not going to but I just feel that way. She's just vey toxic sometimes. I can't stand it and I don't know what to do. I try to just avoid her but sometimes I can't. I can't do anything for me in fearing I will be brought down by her AGAIN and AGAIN. Idk what to do anymore...
