I have trouble making decisions when I'm on the up because I want to do everything and when I'm depressed I want to do nothing. When I'm closer to my baseline I'm awesome at making decisions. I know exactly what I want and there's no second guessing myself.

As for the obsessions, me and my girlfriend say they're my periods of hyperfocus. There's nothing she can do to pull me or my mind off whatever random thing that has it. And if she does manage to get me away from whatever I'm obsessing over I get really mad. My thoughts tend to stay fixated on one thing and no matter how hard I struggle to get off of that one topic my mind always seems to go back to it regardless.
