Is there a mechanic in the game when if you have a gun and you're at low enough mood to self-harm, the character will actually shoot themself? In one of my recent runs I think I managed to stumble into getting stuck in a big ditch with the mentioned gun after getting my jaw annihilated by a spike trap, and I kinda wished it could just be over sooner... aside from using the fast-forward button that is.
Yeah, this game seems to have lots of ways to change emotional state, like seeing corpses, eating something yucky, going through withdrawal getting hurt, or even just sleeping on something uncomfortable will make your character sadder, while taking your time, eating tasty things, and consumption of drugs makes you happy. I'd imagine that also communication with the survivors makes you happier, I just never really checked.
