I feel trapped and trodden on?

3 months ago, after applying to college in UK (not uni, I'm 16) I found out that I was rejected from my dream college, because I was out of catchment area. I had the grades, but I didn't get in. All of my friends got into this college, and I had to go to a statistically and socially bad college. Most of the people in this college are re-taking GCSE's. I don't fit in with any of the people from this college, so I have no friends. All of my friends that went to the other college made larger groups of friends, and forgot about me. It feels like college is trapping me, like I'm worthless, and never going to get further in life. Instead of going to one of the best colleges in the country, and walking round the grounds of Winchester Cathedral at lunch, I walk home, alone, because I have no one to talk to. I have to spend 2 years at this college, and I feel like I can't cope that long. Its not an academic college, so I doubt whether I'll get the grades to go to the university I want. I feel that being rejected from this perfect college, and being put into a drop outs, honestly crap college has ruined my life, and any positive prospect of a future. I just feel trapped and don't know what to do. Everyday I just wake up feeling empty and alone, and pretty soon I'll hit breaking point. Just knowing that my friends have left me, and going to get further in life than me make me feel so empty inside. I don't know what to do with my life. I just don't want to deal with this.
