I Dont Make Friends Easy

I've been told I need to open up to my coworkers more.
I don't really talk to them unless it's work related and I never go out with them.
It's not that I don't like them or have something against them it's just that. . . They gossip...a lot about everyone.incluiding each other so I don't wanna be part of that or let them know about my life.
Have you ever been in a similar situation?
