Please guys pity me. Help me answer my question. I'm really an idiot.?

i'm 15 years old. I study at state school. I just realized that all of my friends including my crush, my best friends lie to me and hate me because of my personality. I just know from my friend, who i can trust, she told me that everyone hates me and they don't honest with me like i do with them, she also admits that she not honest with me because i'm a straight person. I don't really like to tell lie and i've never complements anyone in the class. That's make them unhappy about me and hate for a long time. Some of my friend they just pity me. I don't know what to do. I don't know who should i trust? I completely lost. The most pain of all is to know that my best friend lie to me and hate me. When she told me that i suddenly think about the action that i can do for my best friend and i realize that he won't never ever do it back to me, my crush which i really love also hates me because one of her friends said to me that when she hold my paper and she don't know that it is mine until her friend told her that it is mine, then she doesn't want to hold it anymore. She gives it back to them and said she has to wash her hand because she hold my paper. The person that told me is a girl who sponser by a charity and i've studied with that girl for a long time and i know she won't lie to me with that kind of things so I believe it because all people around me including her some best friends told me that she's really hate me. when she first told me that she said that i don't know what to do but just smile and respond back "I know" because i don't want anybody to know that i secretly love her. You know It's really hurt when a girl you love said that kind of things and my heart just break into pieces. What should i do? And who should i trust from now on? Please help me. .:T0T:. This question i already post but they misunderstood my feeling so i have to post again. I just know how dumb am i. I'm such a idiot. :(
