I need somebody's opinion, please!?

I am 14 years old, and I have one best friend who's really good looking really popular, and is really nice and has a good heart. We become friends 4 and a half years ago, and in first few years it was grate, I remember, and it was like a friendship from the movies. But than, lest's just put it as a guy that we bout liked chose her, not that I had andy chances anyway, and not that that has anything to do whit what happened later, because I didn't care, well, not a lot at least, but in a way , it opened my eyes that in a way she is forgetting about me and because she spend time with everybody else so much, she didn't have time for me at all... I told her this, many times, but I guess she just got tired of hearing it, since she wasn't doing anything anyway, and we ended up fighting every time I would mention it. I tried not saying anything, but I would feel so bad, like there was something in me that I want to release, to get it out of my system, like it was poison, so it went on and on, and in the sumer, we ended it, we were bff's but we become just f's, who would just call each other to tell each other what's happening, and we were still very much separated. It was one of the worst times of my life. Since than, I have bean fighting and dealing with it every day, the fact that she want's to be friends, but she doesn't want to spent time with me. We bout made new friends during the sumer, but, later, my friends started liking her, and we would hang out all together ( my friends, me and her ) At first, I wasn't ok with this, but later, I started adjusting. We R going in different high schools, and I still am going to keep in touch, but after this, the fact that I guess I wasn't worth it , hanging out with, and spending time with, and paying attention to, I'm afraid that the new kids in high school aren't going to like me. I'm sorry if this was a very confusing question, but sometimes, I just feel as if I should get professional help, because, I have no friends left to ask for opinion, and nobody to talk to about this. I appreciate the help
