Anyone who has suffered from depression and has sought any help or done any research will know that 'positive thinking' is often touted as the most effective way to get better, either on its own or in conjunction with medication and other treatment. You are often in essence told that it is your fault in part, that you have to THINK BETTER. You are in control of your thoughts and that you must change these! And voila, there you will be on the path to a better life. I disagree. I believe positive thinking and being aware of your thoughts is good for general self-awareness and to grow your mind and get more in tune with your spirit even. But I don't see this as the holy grail or cure all. "Perspective" cannot fill a hungry belly if you are hungry and starving. Also, you cannot be stranded out in the freezing cold with frost bite, and "think" yourself better or think yourself warm. My point is that while this is admirable and we should all (not just mentally ill persons) try to be conscious of our thoughts, just changing this is not really a solution in many cases. It is not even a start. You may say ok, well if you are stranded in the cold, at least you can think positively and keep hope alive that help is on its way, and try to use that hope to keep you going, one more day, then another and another. But....in reality, there comes a point where even hope is a burden too overbearing. Having hope can make it all worse. That drop you get from disappointment after igniting that flicker of hope, is worse than if you had not expected or hoped for anything at all. As Nietzsche said: Hope in reality is the worst of all evils because it prolongs the torments of man. There are times when you literally NEED a change in circumstance that is often entirely out of your control. A miracle or divine intervention even. Something "needs to give"...but there you are with nothing "giving" yet battling yourself to think positively. Aside from being woefully insufficient at times, when does positive thinking cross over into delusion? I wanted to add something about endogenous versus situational as well, but I think I will end here, as I already don't even know what the point of this post is exactly, except I guess that it all feels rather pointless, and a waste of energy that is in such limited (near depleted) supply.
