Do what it takes to get better but I believe physical and mental are one in the same and you can use one or the other to affect either. Do you exercise? (I'm talking about serious long hikes or other physically exhausting yet stimulating activities). Because that is one of the primary natural things to make you feel better in every way. Lack of exercise is IMO one of the primary contributers to depression. Another IMO is eating crap for food. Many people today still fail to see the connection between food and exercise to your health (both mental & physical). I could rant about how I feel about "The medical establishment" but I won't. Suffice it to say it's only respect & value to me is for Emergency services only. But for chronic ongoing (not immediately life threatening) problems I believe in mans ability to help himself naturally just as we've done in the long forgotten ways of the past.

Nothing wrong with that, and indeed i do agree on all fronts, but not everything can be cured by living a healthy life, we all know that.
But sadly, far too many down-play just how dangerous Depression can be, and that is a pet peeve of mine, because i know first hand that it is a life threatning desease if it is allowed to take control of you for too long.
And whats worse, it changes you, it changes the way you think and act, and it prevents you from really thinking things through, your attention span dwindles to nothing, you cant concentrate on anything, you loose intrest in everything, and you start to have strange thoughts.. at first you know they are strange, but all of a sudden they not only seem normal, they make perfect sense to you! and you dont trust anyone, you dont want to talk to anyone, you fear what they might do or say if they where to know how you feel, so you hide it, you act like nothing is wrong, so even the people clousest to you may never know you are sick.
Once you are in that dark place, you cant help yourself, you dont even want to, hell, you cant even see there is anything wrong with you anymore.
That is why Depression kills, its not because it makes you sad, it breaks down your very survival instincts before it strikes, and breaks down your abillity to see what is happening, and then it is too late, you can nolonger help yourself, and since you have become so good at hiding it, others may not know that you need help.
It is very serious stuff, and it is vital that it be given the respect it deserves, Depression is as deadly as cancer if it goes untreated.
