If you were to ask Jeff and Val (who saw a LOT of my last depressive bout first hand) they'd tell you that I wasn't unhappy so much as that I "wasn't".

I'm also reminded of something that happend during my second depression. A friend of mine took me to a doctor, who asked him if I was acting differently. He said, "This isn't David", while I just stood there thinking, "Yes it is. This is what I'm really like deep inside."
