I think she herself could use some medication since it bothers her so much. She is defintely jealous,and if not jealous, she needs help. Don't let her get to you as that is what she is trying to do. On the other hand, maybe it is a way for her to reach out by using you as her scapegoat.She definately needs help, maybe you could help her, you may even become friends if she breaks down. It sounds like she already did breakdown at you already.
