Is this Virgo once again not fitting in?

One of the great things about college is figuring out who you are; what you like and don't like. Over the past couple of years, I've found I don't fit well into groups. Even more, I don't fit in well with people who aren't very encouraging, competitive, immature and wants to do things at the last minute. I've realized I don't communicate well with people though I've taken classes, read books and so forth to help with this. One thing that doesn't help is that I am a minority, a loner and older than my classmates. These characteristics that are playing against me instead of for me. I'm tired all the time and people think I'm being negative against their ideas. Really, I think very, very logically versus flighty. Lately, I've been irrational with their stress and mine.

On top of it, I feel alienated from the team I'm working with in school. I feel my team members and my professor all seem to be a part of the team and I'm on the outside. I guess I'm not a "groupthink" kind of person and feel this is against me. I don't understand why I don't follow the crowd or tend to alienate against people.

I know there's a game to this, but everytime I get the answers and do it for myself, I fail. People have offered advice, but I don't seem to follow it correctly. Is this normal? How do I offset my emotions or the need to run away? Is this the Virgo in me or what (lol...gotta throw the astrology in there for fun)?

Thank you.
