I agree that it is just a label. Human beings feel most comfortable categorizing things, and its unfortunate that we do it with personalities.
I used to take medication, but it made me feel like a zombie, so I opted instead to just figure out how to cope with my mind.
I feel like a lot of very brilliant, creative people end up being labelled as bipolar or otherwise insane. I would call myself artistic and intelligent. I have always emotionally and mentally been an outsider, so I have had a different perspective on society. Much of the time I think I feel the way that I do because I am so overwhelmed by the sadness that I feel for humanity, and because of this sense that I am not really meant to exist. Which yes, sounds crazy, but I have felt this way for my entire life, and I have never really been someone anyone would call crazy (at least for any extended period of time...I've had my moments).
I don't know. I guess reality just drives me crazy. I have found solace in meditation, yoga, things that help me clear my mind.
