Do you have a social life? Do you have friends? Even if you're not happily married with perfect little children, friendship can bring tremendous purpose to your life.
I do have friends and kinda have a social life, it's more a case of I'd rather not. What I mean is, I consider them all a little immature and even when I'm out with them I tend to feel like I'd rather not be ha.
Yeh I'm sure that sounds strange but that's the reality of it.
