i need some advice/ help.......PLEASE!!!!!

Well...you shouldn't cut yourself for starters. That should be your first concern not a girl who said that and you say is NOT your best friend. And if she said all that to you even out of anger she isn't (I wouldn't think) a real friend. As far as what you should do or say to her...I haven't a clue. Just tell her how you feel.

This girl is definatly not your best friend. How can she call herself that when she said to you what she did?

When my friends found out about me self-harming they were there for me and told me that I was special person and didn't need to be doing that to myself. They didn't call me worthless like your friends did to you.

You need to dump her and find some real friends. Cause lets face it, with ''friends'' like that who needs enemys?
