Gadzooks.... not to go Scientology, but I think the medical profession is very quick to jump on mental irregularities (and thusly prescriptions) vs lifestyle and attitude...
A lot of the shit they throw down your gullet is a "high" vs ppl that are actually in need medically (true bi-polar, etc... One Flew Over the Cuckoo's level). There are documented and accepted symptoms like post-partem... but problem is, everyone is quick to jump on the problem, and remind the patient that it's ok, and let it continue. A LOT of the human condition is self-remediation... and mental should be no execption, sans chemical or severe/hardcore trauma.
I think meds and psycho-analysis and responsibility are in order, but nowadays, the slightest of mental skew seems to be a bit too overwraught with throwing the lifesaver and inducing remediation.
