I've been working in a temp job for 4 months and get along well with all my colleagues. We joke around at work but that's the extent of it. I don't really have anything in common with any of them. I found out today that one colleague is having a party at her house and she's inviting a bunch of people from work but I am not invited. It's making me feel bad like they all hate me. It's also making me worry that this will not turn into a full time position if my manager hates me too. I don't feel close enough to any of my coworkers to bring it up and I feel like it would isolate me more. It also makes me wonder what kind of vibe I'm giving off that repels people.
