I know how you feel. I was bullied out of two different schools - at the first one, all my friends stopped talking to me and this one girl started spreading rumors about me saying things like I give guys blowjobs after school and that I said I wanted to run her over with a car (and I NEVER would do, say, or think those things). It got to the point where literally no one would talk to me because they thought a was an evil whore. When I would walk down the hallway to my locker, all the girls in my grade would turn and look at me, whisper to their friends, make faces at me, and yell degrading names at me. I told my mom and she was so horrified that these happened to me, and she contacted the school about it. They sent me to the counselor who literally told me "Oh well, girls can be mean. Just ignore it!" And the school didn't do a thing. I became really depressed and suicidal. It's a good thing I got out of that school when I did. At the school I attended afterward, things went really well for a long time until my 'best friend' became friends with this other girl and started ignoring me. I befriended this other girl, but she was seriously crazy (I'm not trying to be insulting. She literally had a ton of mental illness problems) and she would get mad at me and just tear me apart out of nowhere. And then, when I would stand up for myself, she would get angry and spread nasty rumors about me so no one would talk to me. And it worked. And then she'd want to be friends again, and the cycle would continue. And again, the counselors/school didn't help. Eventually I finally just told her to go fuck herself (not my exact words.. I was more tactful :P) and I forgot about her. My family ended up moving away that year so I never had to deal with her again (except for the apology messages every month which I finally told her to stop sending and then I blocked her).

So now you know, I totally get what you're feeling/going through. And I'm going to give you some really good advice, so listen up. - Tell your parents. Or at least the parent you feel the most comfortable opening up to.. for me, that's my mom. There isn't any reason to be afraid (unless you did something wrong). - Stop letting people get to you. Over the years I've really developed a thick skin when it comes to people saying things I know aren't true/calling me names. You have to realize that these people aren't worth your time/thoughts and let them say all they want.. You know who you really are, and they don't. - Stand up for yourself. It might be scary at first, but you just have to force yourself to do it. It will get easier. In my case, it didn't always help my situation in the way I wanted, but it gave me a lot of confidence, and I could never say I didn't try to do anything about it. - Go to a counselor. I had really bad luck with my counselors, but that doesn't mean you will. There are some good school counselors that will actually be able to help. - If you don't have any friends, join band or choir or a sport or something. Anything that catches your interest. Or start doing volunteer work. Really, anything! You just have to put yourself out there and you'll make friends. I wish I would have done those things when I was having problems in school because it probably would have helped a lot. And if you somehow still end up with no friends, then you just have to learn to be your own friend for a while. It sounds really sad, but those years when I was bullied were really important to who I am today. Not only did it make me a nicer person (I experienced how awful it feels to be treated like that, and I promised I will never make anyone feel that way), but it helped me understand myself/who I am and what I believe and it made me way more comfortable with myself.

Sorry this was so long! I hope I can help you, and if you have any questions or want to talk, you can PM me. :)
