Haha... I know exactly what you mean. When I first studied biplolar and found that I had it. The doctor told me I will get certain "feelings". He basicly made a "manic" state out to be a beautiful thing or, "euphoric" as you said. Well, when I was noticing the different states of bipolar disorder that I was living, I started wondering. I hate myself at the moment, but really, I kept obssessing and delving into why and my thoughts would make me dive into this mental "black hole". I am glad you brought this tipic up because, Yes! I belive that you can be manic and be in a really crappy mood. Although I cannot speak for everyone, I belive that alot of us bip's can realate!
