I feel bad for these people. They don't deserve ridicule, that's what gets them to do this stuff.
To be frank some of the stuff this girl is talking about is quite relatable to me, thank god I'm going on antidepressants first thing tomorrow. It's really not fun at all to live when you have no motivation, energy or attachment to anything. That's what gets people to rationalize doing stuff like this.
EDIT: Just want to make sure that no one has to be worried about me or anything, I'm rational enough to recognize that this is a mind altering disease and not actually what I "truly" think
