I'm actually kind of surprised about how many people are not aware of the suicide concern. But then, I worked for a couple of years at a large training site where suicide awareness was a Very Big Deal so perhaps I'm just suffering from transference. The symptoms displayed by Mark here are very similar to some kind of "classic" pre-suicidal actions (i.e. "putting his affairs in order") so I can definitely see why suicide would be a concern among his friends.
