...get the urge to go mental and just break stuff. it generally happens when i'm feeling down, like if i'm sitting alone at home or if i see someone walk past who looks happier than i could ever hope to be. i never go through with it because i'm pretty laid back and chilled out and i can totally control myself, but i'll feel the anger rising inside me and have little daydreams where i go totally apeshit and beat the absolute shit out of people and break everything.
shit man, i get that too...i'm a totally nice, down to earth person...relaxed and laid back, but sometimes i'll just get the urge to go crazy and snap lose it...it's usually just the urge to break everything in sight, especially easily broken things like glass and shit sometimes i get it when it's provoked, ie. something shitty happens at work, or someone does something/says something but other times it just comes out of nowhere...mind you i never actually do anything, but its weird when the thoughts come into my mind
i have similar thoughts except i have really intense thoughts of killing my cousin (who i live with) more often though, i have thoughts of killing myself when i do have thoughts of breaking shit and stuff like that its so intense that sometimes i can barely repress it
