OK, a little bit of a clickbait title. :)
Well slightly, not totally. I remember back in the early 2010s there was this user on PsychForums named JustOneMorePerson. And he was a self-proclaimed psychopath who worked as an EMT. Actually I'm inclined to believe he wasn't a liar after reading enough of what he had to say.
But he had an interesting take on depression which stuck with me, which I think is actually true. It's in my head because I was discussing this with someone yesterday, maybe sharing it is worth it.
His take was that depression is a social selection mechanism, which takes you out of the social group via suicide, in order to benefit the group. And that's kind of true...we are primates, and if you don't have a "tribe", that is when most people start to feel depressed. Some say chemical imbalances...you know I buy that theory less and less every day. In fact low serotonin is probably a good thing. But that is a tangent.
So we have this mechanism as primates which takes us out of the social order once we become isolated. Because within the environment we evolved in, isolation would almost always happen in the context that you were rejected by your social unit. Since no one could really survive on their own. Depression is a lack of meaningful connection, and the reason why depressed people kill themselves is because that is how they are hardwired to not hold the group back. It's like how dogs when they are dying go out to be isolated in a cold spot.
In my personal experience I see this more and more. The homeless people I interact with who give up on everything, in general they have all been abandoned. No social network to speak of. And that might also speak to why I never feel really depressed, because even at my lowest points I have friends, and I'm social.
So what is the takeaway here, tl;dr? Firstly that it's of extreme importance that you belong within some social group. Otherwise your biology will try to convince you to take yourself out of the way. And Secondly we must not forget who and what we are. Primates are social animals, and none of you are exempt from this. Well, that's the end of my rant, I hope some of you enjoyed.
