One thing that helps me when I have a sudden mood change (like from irritability to anger to rage to depression, etc. in a very short time frame) is even though I'm thinking revengeful thoughts on people who've been mean or misunderstanding or completely careless and ignorant to me, I say to myself "These are only thoughts and they don't make me a bad person and I don't have to act on them. Take some time, calm down, have a nap. This will pass." My brain chemistry feels all messed up during & after one of these rapid cycle moments and it usually exhausts me so I go to sleep for a couple of hours. And I don't know if the music you were listening to was making you feel good or triggered you or what, but I am really bad about listening to depressing music when I'm already depressed, and I know it can't help. Angry music when I'm angry also. Argh. Why can't life be simple, ya know? So it goes being bipolar or having any mood disorder.

But you're okay feeling and thinking things. Just tell your docs what you're experiencing and call someone if the urge to act on anything destructive becomes practically irresistible.

Let us know how things are going.
