I worked with the public. I was constantly stressed out and kept away from my coworkers I actually got along with. I always felt "alone in a crowd."
I'd lie if I said thoughts of self-termination never crossed my mind. Only one or two of those coworkers actually kept up with me when I left, too.
I get a little lonely at home now, but I'm with people I love, and I make time to talk to people by choice.
Quality over quantity, I'd say.
