I think it's important to remind ourselves that sometimes people aren't always able to give us what we want or expect, especially when they don't know our expectations. It can be helpful, if you feel confident enough to tackle it, to approach people and directly address the issue. "I'd really like to get to know you better and form some good relationships here. Would you be interested in talking for a few minutes sometime?" It can be difficult to put ourselves out there, but at least it gives us an opportunity to express our interest and try to get our needs met rather than letting them go unnoticed.

The other thing is that sometimes we assume things about other people and their motives or interest. This might be a cognitive distortion like "Mind Reading" or "Fortune Telling," or it could just be our own anxiety and insecurity getting the better of us. It may not be that they don't like you or don't want to be around you. It could be a variety of other things such as them being too busy and focused on their own problems, them being stressed due to their own work, or them being anxious themselves and not knowing how to approach and welcome you.

You're right, it is good just to have a job right now. But that doesn't mean you have to settle for a work environment that is unhappy. Good luck whatever you decide to do!
