I've been a bit down lately (I struggle with depression), and just feeling very alone. The only person I really talk to regularly is my fiancée, whom I love to bits, but we don't share ALL of the same interests and sometimes I feel like it would be nice to have someone to kind of geek out with. I've always been terrible at making friends though, and I really have no idea why. I think it's just a combination of my anxiety messing with me anytime I feel like I could potentially make a friend and my depression making it so I'm not always ok to go out and do anything.  
Has anyone else had this issue? Is it bad to want someone other than my fiancée to hang out with or talk to?
