I feel broken

I came out to my "best friend" today. She called me a faggot. She told me that she could never be friends with someone who is a lesbian. She called me a dyke, too. I feel so heart broken. Before today she said I could tell her anything. I never had a crush on her but she was the closest friend I had. I wish I'd never told her. I feel awful, worthless, disgusting. Why would she say those things? Why do I have to be this way?
