Romance in My Life... What a Disaster. Help Me!

Ok, so here's this guy I love like hell. I know all of you will think that it's just an infatuation at my age but, trust me, it's not. It's true love. I've cut myself for him, I have sleepless nights for him, I have dreams about him when I actually sleep and I cry for him daily. He knows that I like him. He doesn't know that I love him more than anyone else ever would. He said "Oh, she's just a kid. Tell her to concentrate on her studies." when I told one of his friends to tell him. Now, that one friend of his, loves me. Argh, I'm just tired. There's a boys group in our neighborhood, and two boys in that group were and still ARE in love with me. Once as a stupid dare, one of my friends told me to tell "I love you" to those boys. BOTH OF THEM. Since it was a dare I had to do it. :( But BOTH OF THEM thought that I actually felt that way about them. And they have been spreading ever since that I am a cheater and I do not love anyone and that boy I actually love has also heard rumors about me from them. That friend of the boy whom I love also heard it. And now, I have three lovers, (that too crazy mad lovers) and one whom I love. This guy whom I love is 18 years old. I'm 13. People who know about this thing say it's too much a difference. But he can love me. My instinct says so. If his friend who is 19 years old can love me, he can too. But that's the problem. Even if he will love me, he won't trust me. Because of those fatheads and their rumors. WHAT WILL I DO??? HE JUST THINKS THAT I'M A BIG FAT CHEATER AND HE IGNORES ME AND HATES ME AND THINKS THAT I'M JUST A KID AND I SHOULD STUDY! AS IF I DON'T ALREADY GET HIGHER MARKS THAN HIM!! EVEN AT MY AGE HE WASN'T AS GOOD IN STUDIES AS ME! WHAT WILL I DO?? HELP ME!! And on top of that I'm not on Facebook. I can't tell my parents that so much is wrong in my life. So they think that there's no need of me having a Facebook account and a phone and MY OWN PRIVACY. All those guys are all on Facebook and I don't even get to know what things and stuff they're posting about me. Even if I have a Facebook account (fake). But still. HEY, NO ONE'S SUPPOSED TO KNOW THAT!!
