Friendless &Amp; My Mom Competes With Me With Everything

I recently moved to a new town to go to college and have been here about 6 months and still dont have a single friend. Granted I left my old drama filled town with no friends so it makes it even that much more lonely here with no one to talk to. I don't understand if I am a ***** or just dont look friendly enough to talk to but even when I talk to someone and try to become their friend it never happens. To top it off I finally met my real mom and she is young since she had me at a young age but she constantly has to do better than me. I dont understand it you are supposed to be happy for what your childs accomplishments are not try to out do them. Like when I am in a relationship and she is to she is happy but once her relationship goes to **** she has to try and ruin mine for me too. Or if I get something she goes out and buys something better. It wouldn't bother me if she didn't sit there and try to rub it in my face. To top it off I applied to volunteer at a fire department and she has been a firefighter for a while so I told her she could apply for the firefighting and I would start off as a dispatcher so I could move up. Instead she took my position just out of spite. Seriously we could have worked together if she wasnt out to have or get everything I want. If she is introducing me she says this is my daughter and starts going off about how much better than me she is. This sucks because she is the only person I know right now and I have to spend so much time with her. I feel so alone that I feel like im on the verge of depression and I don't know what to do.
