Honestly most people I've met who are depressed are just mentally weak people experiencing first world problems. Yes there is that 5-10% that truly have a reason to be, but that's a very small minority.

Depression is not outside of your control. This encouragement of that kind of thinking classifying it as a "disease" is what keeps people depressed (and makes doctors money).

Was reading a book by a now successful guy who was suicidal all throughout his teenage years. He said that feeling suicidal was one of the best things to happen to him because it gave him this risk-taking attitude to just make the bold moves to turn his life around, because if things didn't work out, he could always kill himself.

Honestly it's unfortunate that this is considered too touchy a topic to talk about. We'd have less suicides if we could openly talk about it, and maybe you're committing the sin that you're accusing me of.
