Depression is when your opinion of yourself is disconnected from a reality which you can no longer ignore.
That's all it is. Nothing more, nothing less.
Everything else about it is window dressing, extraneous irrelevant bullshit designed to mask this obvious truth.
Acceptence is the cure. People should just accept how shit they are, and love themselves anyway. IT'S EASY. And you don't need drugs to do it. Just decide to do it.
So, we should be letting children be as shit as they are, rather than force them to maintain some ideal of perfection which 99% of them will fail to achieve. Tell them they are crap, but being crap is OK and we love them anyway.
Don't tell crap people they are great, the truth will out in the end and when it does it will fuck them up more.
I'm never wrong...
