OK... Further to my other post...
Clinical depression covers BOTH endogenous depression (from within, no visible casue) AND reactive (situational) depression, which is caused by an event which most people woudl consider "depressing" - clinical depression simply means that the symptioms are observable, and have remained so for a length of time such that a clinical diagnosis is warranted.
GPS are not always in the best place to diagnose efficiently, and with the best results, anti depressants are the quickest, cheapest and fastest acting thing to dish out to prevent actual death. Changing your prescription to a new drug does NOT mean you need "stringer" meds, just that you need "different" meds.
Bipolar is not rare - 1% of the population is a LOTS of people (of which only 17% are able to sustain a full time job - largely imo as a result of stigma and lack of understandning)
Schizophrenia is ANOTHER 1% of the population
so for every 100 people you walk past in the street, chances are that 2 of them have one of those "severe and enduring" diagnoses - and that's just those two diagnoses.
However, "depression" is a term that is bandied about a lot, and which it is, for the person who WANTS to, fairly easy to get diagnosed with, so it's not unimaginable that some people will play the system.
This does not make depression any easier to deal with for those peoplew ho actually have it.
"Happy" is not the default setting for huimanity, one is not unwell purely because one is not happy, so no one should ever think that ADs will make you HAPPY, they won't, they will (if you are on the right one) improve your chemical balance and make you more able to cope with the reality of your life in a positive way. Just like taking insulin improves your chance of NOT dying from diabetes, but does not make you happy.
making oneself WELL is not the same as being happy, and people with depression just want to be well.
I have tried most ADs currently prescribed, I am not allowed to have them any more unless I am IN hospital, as my bipolar includes "switching" so ADs flip me into mania REALLY quickly. IT IS possible to have a fullfilling, rewarding and NORMAL life (I have post graduate qulas, and other than several long stays in hospital have worked full time, until maternity leave / SaHM)
