7th Grade Romance, what do I do?

I just finished 7th grade and it was the worst year of my life. My best friend was dating a horrible guy who was my worst enemy. My worst enemy's best friend was my crush. When I told my best friend who I had a crush on, naturally her BF found out. My enemy blackmailed me, saying he would tell my crush I liked him... and every time I've ever told a crush I liked them it never worked out. Eventually, he told my crush, and then my crush never spoke to me again. He blocked me on Facebook and I have no ways of contact with him. It hurts because every night I remember every happy moment we ever had together because we were really close friends.. and then I cry. But at the same time I'm so angry at him because he said I made his life a living hell and that he hated me. And he even calls me "It" when he talks to his friends. I went to a party and he didn't even come because he knew I was going, even though all his best friends were going to be there. He always acts as though he thinks I get everything handed to me just because I make really good grades and I got school academic awards, and even an award for taking the ACT's this year and did pretty good (scored a 23 overall). And there's another guy who I'm interested in and he's in my algebra class, but he's a year older than me and is going into high school when summer ends. I tried to show my feelings for him, but he simply said he likes me as a friend. So we're staying as that for now. I feel like everyone has a boyfriend except for me and it makes me really sad. At least my enemy and my best friend broke up so now I don't have to deal with that, but now my best friend is dating a guy who is two years older than her, which I guess is okay... but I keep feeling like everyone hates me and never wants to talk to me again. And I decided to change schools into a magnet school because my grades certainly qualified, but I keep having second thoughts about staying at this public school even though I feel horrible. And I just want to make everything right because I feel like a jerk who has no friends... will someone help me?
