Feeling lonely

I feel so lonely right now, I live far away from the one real friend I have, and in my class there are 3 main groups of people and I don't really belong in any of them and I don't feel that any of them really want me there. Also I thought I had a friend in my class but now she's hanging out with other people and doesn't care about me anymore. Things aren't going great with my boyfriend either. I'm not asking for responses, I just wanted to get it off my chest. I feel like I have no one.
