First I just want to say WOW! What a supportive husband you have when it comes to your illness. That is hugely commendable!

Yes, I do the same thing. Especially when I become very very manic, I become hyper focused on a subject (religion, politics, theatre, etc) and become all encompassed with it. It's like my very being collides with my passion and it becomes my life, my everything. I want to change things, better things, understand things that others just seem to let go. It is both maddening and saddening. I also feel like I know things that others can't possibly know; I believe that I have understandings that others cannot possibly grasp.
