Serious help please?? Kind of an important problem..?

I would try to get her out of your life, she clearly isn't your friend. Yes you should definitely make new friends. Destructive people like that will only cause pointless drama and problems for you. Try to find friends who are positive and you actually like. To find new friends you could go to clubs, talk to people in class you usually wouldn't, join a sports team, talk to people at the mall. Could you use paragraphs next time, would have made it much easier to read.
