How about, if she annoys you so much, you tell her exactly that. Tell her that you don't want any part in her pointlessly dramatic bullstuff. She's not your friend if she annoys you, and at this point she's just being a hormonal angsty teen so be the better person in the situation and stop talking to her if she bugs you. If all you talk about is her problems, that's a stuff friendship anyway so just be a little harsh: Shelbie, I'm not willing to help you with all your issues anymore. You annoy me, and your angst makes it really difficult to be friends. In just this last conversation, you told me to shut the forget up and tell you how to delete that guy when I was trying to be helpful. I'm done.
that's what I would say :|
