Realizing it's your BD is a good first step. I've done some massively stupid things during episodes - smashing a laptop that was acting up, ending relationships I later regretted, quitting jobs. ...But also some that ended up being good, like running away from an abusive home.

To be honest, your life MAY be bad enough to be worth running away from.

...But it's a crapshoot, and while you're in this mood, you probably can't trust your perceptions. Do you really want to gamble with your life?
