When I get way too "into" a certain project, person, or outcome, where I feel invincible and overly confident, when people try to bring me back down to reality. I get angry and upset at people who I perceive as trying to ruin things, when really they want to steer me away from bad decisions. I'll make plans way too fast and think I can take on the world, without thinking about how much something will cost or the risks that come with important decisions. My sleep is never really that good, but I sleep less when manic or hypomanic. I can be up for hours and hours without feeling the need to sleep at all. Eventually, it becomes full-blown mania, until I finally crash.
