Yeah I absolutely behave this way and am known in circles for being the life of the party... When I give a shit (usually games, lan parties, paintball, SOME parties, real pressing deadlines, anything really specific that I enjoy). It's like both the logical and intuitive sides of my brain are perfectly in synch with ALL the dynamics, logical and social going on around me. It's such a weird feeling of, for lack of a better word, dominance, that I can recall it for weeks afterword. The hard part is the fact that I'm naturally shy, KNOWING I have that side of myself inside me but having no way to access it, and knowing I barely have the energy to put myself in situations where I can access it, can really be tortuous. I was depressed for a long time in my early to mid twenties, wandering thoughts, obsessions with people and concepts. Really the first thing to drag me out of it in a sustained way has been a relationship with an ironically adhd hyperactive woman who is constantly getting me to do things even when I feel like I don't have the energy.

Anyway, I had no idea this was a maybe-sorta-kinda different disorder from innatentive, but going down the symptoms I have pretty much every one. Definitely something to talk to my psychologist about.
