Just last month a relative commit suicide. He was diagnosed with multiple sclerosis about 4 years prior, which he continued his drunken/doped up lifestyle for two years with the disease until it grew into a debilitating state as he was losing coordination and balance and within the last few months of his life was having trouble coping with it, as it gotten worse... He eventually turned to anti-depressants which altered his moods drastically from day to day.
His doctors threw every kind of medication at him they could, he was on supplemental income as well as state funded insurance, could it be these doctors were really just pharmaceutical salesman? His condition never got any better, but they were always ensuring him that the bi-weekly appointments with neurologists and the $3,000 injections were keeping him alive. I am not trying to make a case for him, as he was a waste his entire 38 years of life, no family.. never had a real job, lived at home with his mother, and was a huge asshole.. up to the day the hung himself.
I feel anti-depressants are in place to let people cope with life's difficulties in the most passive form... pop a couple of pills and everything will be alright, or so they tell you. You feel too chemically good now to worry about the future.. In a world where everyone blindly denies reality in favor of their own hedonistic ways, this is how problems are handled. Let them go for as long as possible, as long as you feel good at the moment. Most of the people I know who have taken them, abuse them to get stoned on.. Just like any other temporal drug.. the problem is never solved. It will keep chasing you, and eventually catch up.. like it did my uncle.
