I find myself either the cold, empty, unsociable, low self-esteem me or the confident, fearless, positive charming me. I've tried to be sociable when I can't feel anything. It doesn't work.

I don't know what the hell this is and I don't know how to control it. It doesn't take a lot to change me from confident to cold, even my own misinterpretation of events can do this.

How does one go about making the best of one's moods?
