I've been reading a biography on Chris Farley this week called The Chris Farley Show. It has been messing with me too; all week long I've been in this funky depressed mood.
Anyways here is a quote by Chris towards the later part of his life:
"The notion of love is something that would be a wonderful thing. I don't think I've ever experienced it, other than the love of my family. At this point it's something beyong my grasp. But I can imagine it, and longing for it makes me sad."
