How friendly are you with the people at work? Do you eat lunch with others? Do you participate in any water cooler banter? Do you ever pop your head into other people’s cubicles just to chat?
I live in solitude myself. My life is very much “unpeopled”. But at work I try to step out of my bubble and interact with others in the ways I just listed. People may not know me personally, and that’s fine with me. But at least they smile and nod at me when we’re in the elevator together. Little stuff like that helps me not feel so alienated.
Do you have a laptop or tablet? Instead of going home straight after work, maybe you could hang out at a crowded Starbucks for a while and use the free wi-fi while awhile. I know that sounds like a waste of time, but doing stuff like this is my “compromise”. It gets me around people and their energy, but not too close to them that I feel overwhelmed.
Also, look to see if your town has a science pub. I attended a science pub event back in November that was pretty cool. Didn’t make any friends or anything, but that wasn’t why I went. I just wanted to do something in the company of others and absorb fellow “geek” energy.
