I feel like I've signed myself into an insane asylum...
Reminds me of an RP I did taking place in an asylum that was more like a prison, and my character just had anger issues. He would just have been in therapy, but because of an overactive adrenalin gland (Known as Cushing's Disease for any of you medically inclined types), he couldn't be treated unless under restraint, since he was constantly under the effects of adrenalin. He could control himself for the most part, but when he got startled or agitated, he tended to get violent. He punched a lot of holes in the walls.
