I secretly hate my bestfriend

Okay, so me and my Best friend have known each other for quite a long time. but see the problem is she loves believing in rumors, like for an example: Sarah said you cant dress.
Like come on, we've been best friends for a long time!! why would i talk about you. i usually love to be around her, and have long conversations. but now we have short conversations; every time we talk its mostly about her crush, or some girl she doesn't like. we use to be so close but now i may be having second thoughts. she is clearly an attention seeker; "Oh I'm so Ugly, nobody likes me" yes in my opinion she is beautiful but i do have some good things about me. Also My Best Friend is rude and hurtful to people, she makes them feel bad about them self's. but i could say she isn't the nicest person in the world. She Also makes me do all the work in school. sometimes i think with out me she would be failing? I'm not even sure myself. she said that every couple of best friends fight rarely but we have been having fights casually, as you could say more then usual. and i hate it, i wish we could just talk it out but she might not even listen. i cant really say i HATE my best friend,but sometimes i can come to strongly dislike her..? I really do want to keep holding on, and support her and stuff like that, but its becoming really hard to keep this friendship alive because she puts all the weight on me,and ignores the fact that a friendship takes to people not just one. you guys can relate right.? Sometimes i think to myself; that my best friend really, truly, hates my guts, and doesn't even want to be my friend....you know?? and i was hoping maybe she could take consideration, and talk to me so we could work it out. but i'm really feeling like i'm starting to give up everything that "we" worked for. hopefully things start to patch up, because i would hate having this still going on. Anybody can relate right.?
