I didn't get to read the op. But I like the idea of turning a diagnosis around and using it as a benefit (not as an excuse). That's what I thought the thread would be about from the subject line, but it seems like most people worry about using it as an excuse. I liked what Chris wrote about being okay asking for what she needs. Sometimes it's hard to tell what's a need though, but it seems like Chris understands her needs pretty clearly. I think it's cool you're being more open about your dx Chris.
I think I might use my depression as a benefit the way southpole described, for understanding my past. I don't think I use depression as an excuse, as I never call myself depressed (except in a casual way) to anyone except therapists. I don't really know how I'd use it as a benefit in current life... maybe knowing when I need to go to bed earlier or take a break from work or something... I don't know if I could be so sure about what my "needs" are as Chris.
Oh, I also think the person who got the extra space on the plane had a totally awesome way of using a dx as a benefit

. I wonder if the air carriers would let people do that these days... they really ought to give everyone more room to move around for health reasons anyway.
