Thanks guys for the quick response and sharing your experiences. Really appreciate it. I am starting to have a clear understanding of bipolar II after reading all your replies. But as what Mountainbird said, I still have a lot of researching to do. My best bet is to differentiate what's normal and what's not. After I am really convinced, I might go back to my pdoc to get treated, just maybe. If indeed what I experience is hypomania, then I do believe that it has a big benefit. And I admit I like the period when I'm "hypomanic"(which i tend to think of it as the behavior, as a product of my personality). Like I would be more sociable, productive, coming up with ideas and my favorite, writing songs. I also feel less anxious(can sometimes led me to be daring and help me speak up to my fierce dad). When I'm depressed, I just want to be alone and nothing interests me. It would be saddening to take that power away from me How I wish I just have "hypomania" without the depression part... and talking about it, it does seems like I am bipolar
So far the problems I face seems to be due to my anxiety and depression. If what I'm experiencing is hypomania, I don't think it has lead me to any trouble as anxiety or depression has.

I shall document my everyday life and compare it according to all your replies. Maybe it can help me see a pattern. And also gonna read up books on this topic, one that is recommended by Mountainbird, "Bipolar for the dummies" seems interesting. Maybe I'll keep updating about my findings. Thanks again guys, you guys are an awesome bunch
