Is it normal that i hate my best friend

i hate mine best friend. she hurts my feeling almost everyday and over the past 2 weeks has called me fat,easy, desperate and aggresive ... i am none of these things. she also copies everything i do and say just because she can. i have over the time of our friendship introduced her to pretty much everyone she is now 'so close' with. she has started taking my friends away from me including the guy i like who she has been all over and wouldn't know unless i had introduced them. she genuinly laughs at my pain. i have had panic attacks with her around before and the first thing she did was laugh and said well you shouldn't have done it then .... I DIDN'T KNOW IT WOULD HAPPEN DID I... and i have a really bad relationship with my family and she talks about it behind my back making fun of me. but i cant not be friends with her because i am scared that then i will have no one left. i cant tell her anything because i dont trust her. is it normal to hate my best friend? x
