axis 1 bipolar

I have to make a final document and needs to choose an Axis 1 disorder to write about what are my options?
I've been in all local libraries and still can not find the book How DSM4 just want to write about something interesting, I know I could do skzio bipolar, but I want to write about something I'd like to learn interesting new things about.
I think you should stay away from reading about the mental problems will only make you k-worst record
