I get that way when I'm highly manic....maybe not "to death", but I do have the urge to get into a physical altercation. And yes, it's almost physically painful to try to suppress them! I get so enraged that I feel like I'm going to spontaneously combust! I hate it when I get that way because I'll lash out on ANYONE in my path! Fortunately though, so far I've only unleashed on people who UNDERSTAND that it was my disorder causing me to act like that. I'm really surprise that they stick around!
