I don't think it's unusual to want to be alone doing nothing. I get like that when I feel utterly overwhelmed by every little thing. I don't want to be around people because the comparison I make between myself and others sharply remind me of my inadequacies. Sometimes I do need to be alone just to take a breather and recharge. Other times I force myself to be social and remind myself that my comparisons between myself and other are probably invalid. I don't know what's really going on in other people's lives. They could be hiding things and be feeling just as awful as I do.
