The bad side of mania or hypomania is poor judgement and impulse control problems.
It is hard to write about these problems, because personal stories are often embarrassing. It's hard to talk about the stuff you did when you weren't thinking right.
This is why for weekend reading I am suggesting that you read Darcie French's Dear Squidoo letter about the errors she made during a manic episode.
She describes her excessive happiness and hopefulness, her poor judgment, and her grandiose thoughts - all symptoms of mania. What makes her story interesting is her insight into how she was thinking. I really enjoyed reading her story and I hope that you do too!
So that's my weekend reading suggestion..... Have a happy weekend! :)
