Self harmicidal

A state of depression so severe that it produces an excess of extreme hatred and typically directionless anger as well as urges to hurt/kill both both themselves and others. A combination of wanting to self harm and being homicidal.

Person 1: Hey bro how are you?

Person 2: I feel horrible; society sucks, people suck, and life in general sucks! I want to cut my wrists and die but I also wanna just stab anyone who dares come close to me!

Person 1: Damn dude you should get some help before you do something you'll regret! You've become full on self harmicidal!
