I suffer from it. It's real uncomfortable, and I've done my share of alienating people when I'm in one of the opposing poles to my depression. But, meds and therapy help. I'm bipolar 'mixed', my moods cycle rapidly in the course of a day. But then, the whole mess goes dormant and I could be fine for months...years, etc. I never get the extreme mania to the point that I'm delusional or unreasonable and not able to sleep for days (see, Spears), but instead it manifests itself as aggression. I can get 'set off' when I'm cycling and then I'm a mess. At one point, there were 4 web boards that I was banned or nearly banned from because I got so aggressive- and that's just the internet! In real life, I came
real close to losing my job.
I find that avoiding 'Beautiful Child' during a depressed mood helps alot.
You'll be alright..
