*hugs!* Trust me I've been there too. I've worked at places where I've known I'll never be chummy with my co-workers...just because I'm so different from them and have NOTHING in common. I always make an atempt to be friendly, and I'm the type that will just start yapping at someone I don't know just to start a conversation (I used to be really shy and standoffish but not anymore!!) . That really bugs some people though

Find common ground. The fact that you work in the same place is sometimes a good start (Unless you work with people who hate their jobs)

Good luck Just remember, work is only your life for a small portion of the day!
