Used to happen all the time. In fact, I would almost always act on it. Put 3 holes in my old houses walls. So, finally we discovered the reason. I'm bi-polar. Now I'm on pills ((effexor, depakote, and seroquel)) and I've gotta say my life has improved massively. But, now thanks to marijuana and salvia, I've decided to slowly ween off my effexor and seroquel, leaving only my depakote. Just don't do anything too stupid. For example in a fit of rage at the officers in your house trying to pick you up and take you to the hospital because your wrists and gushing blood, don't, say... take the exacto knife out of your pocket and try to to poke one of the officers a little bit in the arm so he'll fuck off and let you die. Okay, personal experience there. Anyway, I was lucky the officer was cool as hell and just sent me to a kids psych ward for 3 weeks ((fucking hell. I swear I've never been in a place so terrible)) instead of pressing any charges or anything.
