One of my new roommates is diagnosed with chronic depression and though I'm not particularly worried about him, I feel I should at least lend him some support if need be. I was curious to see if any of you had any recommended reading or know of a few websites that might help me understand what he's coping with? I would ask him but I'm afraid of offending him but on the same note I don't want to be a dick or add to his problems.

Any info, suggestions or recommendations are appreciated.
