I've changed my sex because of my girlfriend and now she says she doesn't want me anymore. What should I do?

It's been 6 months my girlfriend told me that she was lesbian and didn't want to be with me anymore even though she still loved me. I was desperately in love with her and then I decided to do something that maybe no other guy would ever do for a girl: I subjected myself to a surgery in Africa to change my sex and turn myself into a girl so she woud have no reason to leave me. Last month the whole process was completely done and I hadn't told her anything yet because I wanted to surprise her. However, when she saw me she said that all I did was for nothing because she doens't want to stay with me even after all I've done for her. She said she would never ask me to do such a thing and that I was looking like a monster for her. Now I just don't know what to do. I like girls and I don't know if I will ever find another girl who accepts me the way that I look now. The doctor told me the surgery is unreversable.
