I Will Answer Anything You Ask

Sometimes I feel so alone and friendless at work. I have good friends in my private life, but at work I just don't have so much in common with the people I work with and I find it hard to mix with them. It is like they get in little groups and have private conversations and don't include me, and I also get left out of email loops. I work in a small team and it is the girl who sits next to me who I find most difficult. If I talk to her, she will answer me as minimally as possible, and she is never chatty and inclusive the way she is with the others. Does anyone else experience this sort of thing and how do you deal with it?
