<human>: I've been employed at this restaurant for almost 3 years, but I'm a college student so I only work there when I'm home for breaks. 

This is not the first time I've felt this way at this job but I don't think I can go another whole summer like this. It's hard to put my finger on exactly what's happening here but I feel like an outcast with my coworkers. I know we are all there to work but we have frequent down time but also there's a general camaraderie while working between my coworkers. I do not feel like I'm a part of this. If my coworkers are standing around talking, I have to stand "outside" the group and basically have to butt in the conversation to be a part of it. Aside from a few questions about school when I first return, none of my coworkers have any interest in talking to me, but they do with each other.  If I try to initiate conversation it usually doesn't last and it seems like the other person doesn't want to talk to me. Plus it's difficult for me to break into a group of people that already have inside jokes and are friends with each other. I imagine I'm perceived as awkward and too serious or something, I'm not really sure. Overall this wears on me and makes me quite sad. It also makes my time at this job difficult on a day to day basis. 

I don't want to leave this job, as it's convenient and not bad for a college summer job. I would like to know why I'm in this position with my coworkers and what I can do to make it better, especially if a negative reputation of me has built up over time.

Can you condense the text into three sentences or less?
<bot>: I (20F) am a college student returning to my part time job for the summer. I feel like an outcast socially with my coworkers (18-30 M&F) and would like to improve the situation.
