If you have had one manic episode your considered Bipolar I . It only takes one episode to fit the DSM for the I . I know a few people that have only had one Mania, there medications and lifestyle changes have kept them from having another, which is good ! Having anger outbursts are often part of Mania... Most all my Mania's include anger and non stop irritabilty. I don't get the Happy rainbow puppies.
Glad your liking PC !!! It's a great place to hang and be understood
