<human>: Can you give me the gist of the text in a nutshell?

I don't really know how to deal with this anymore. 

I've always felt like I didn't belong, ever since I could remember. I'm the kind of person that only has a few close friends, and girls never really paid any attention to me other than to make fun of me. There was a turning point for me in high school, my second year in. I was succeeding in the sports that I played, landing in the varsity team in a competitive area. Girls started to talk to me, I didn't know how to handle it because of the previously stated reason. Self esteem was starting to pick up. I met a particular girl that latched onto me and we started dating. I found out that she had a rather abusive home, and devoted myself to showing her how great life could really be. My parents hated her.

Fast forward a few years, past her cheating incident and my immediate family's move across the country. I moved with her to Portland, Oregon. I've never seen this place before, and now I'm paying rent in a crappy apartment in order to get a foothold here. After a few months of depression due to the lack of close friends besides her and the job being minimum wage, she breaks it off due to me not "doing enough to make her feel wanted". Within a week, she's seeing another guy. 

I've moved out, and now have a much better job/career. But my social standing is worse. The one friend I had made in my minimum wage job moved to Alaska and previously mentioned girl broke my heart.  I'm living in a university housing situation at the moment, but I don't get along with these people very well. I don't like weed, excessive drinking, or casual sex. The few people I've had interaction with just keep me at arm's length, and seem to enjoy all the above.
<bot>: Had serious relationship invested one way too early with wrong person, moved away from everybody I care about, said person broke up with me in new city where I know nobody. Cue crippling loneliness for months.
