If he had clinical depression, he may not have been at all thinking straight.
I read these comments and get the impression that none of those criticizing this man have ever dealt with serious long term clinical depression. And in many cases the antidepressants only make the situation worse.
Thankfully now, there are genetic tests available that indicate which ones will be best tolerated for each individual as well as which ones to avoid. GeneSiteRX, is 1 such test, but there are others.
Personally, I don't think I could take my own life, it's not mine to take, after all, but I'm not going to condemn those who are desperate for the pain to stop.(walk a mile in my shoes, sort of thing).
