What should I do in this situation with my mother? I'm SOOOO depressed?

My mother is always accusing me of doing things that I don't do even simple things like going into her room. I hate when she does that and I get upset but she's so convinced that I do these things that she accuses me of. I was so mad and we ended up arguing. She then started saying that when I get married my husband is going to abuse me and then she started accusing me of being promiscuous and said, "I don't know how big your hole is." I was so mad! I still live with my mother since I'm still taking cles and save money but I can't take this anymore. I feel bad to leave because she lives by herself but I get to the point of feeling suicidal when these things happen. She brings out the worst in me. What do you think?
