How do I get my mom to accept me?

Well I'm 13 and I finally found who I really am. This new look she calls "emo". I get really offended. She always calls me goth and a freak. I get really upset but try to deny it or say "Thanks!" and make it seem like it doesn't bother me. I only listen to the band Black Veil Brides because they are my inspiration. They are the reason I be myself and never give in. She often makes fun of me for that and calls me obsessed and stupid. She actually sent me to my room about 5 minutes ago because she asked why I had a Twitter app on my iPhone if I don't tweet anything, and I told her I use it to follow Black Veil Brides and see what the band members do every day. She then said she never wants to hear their name again and called me obsessed and retarded before saying "Get outta my face.". I get really hurt when she makes fun of me. I told her I don't appreciate the name calling but she said "Oh well.". She makes me really sad. I want her to accept me for who I am. I already talked to my father (who doesn't live with us) and he said if I want to be this way, I can be this way because he did crazy things as a child. He even offered for me to move into his house because he will let me dye my hair black but my mom won't. I don't want to move in with him though because he is a heavy drinker and smoker and I still love my mother. My mom always makes fun of me and tells my grandmother over the phone about how I'll never be goth because that will be "over her dead body". I really hate these labels she gives me. I'm not goth, I'm not emo, I am a human fu*king being. On Facebook I posted my status as "The new BVB album is awesome!" and she replied to all my friends comments with "She's an obsessed goth freak!!!" I got really upset and just deleted the post in all. When I got my hair cut like Andy Six (the lead singer of the band) a couple months ago, she started the name calling even worse. I don't cut my hair this way because Andy has it, and I don't dress this way because the band does. I do this all because I am being myself. I'm really damaged by all these things she says an does. Problem is my mother is heartless. I just want her to love me. I want her to accept me. She doesn't understand what damage she's doing..... How do I get her to accept me?
