I figured out I was Bipolar due to my first seriously depressive episode. I had one back in 6th grade, a very serious one, but I chalked it up to hormones. But once depressed, & for a long time, I realized there was something wrong. And not conventional depression. I'm known for running high: insomnia, hyperactivity, nonstop talking, recklessness, grandiose plans, inflated ego, short fuse, dialated pupils, having lots of meaningless sex just on principle, doing more drugs than I normally would, always raring to go. Only when I was depressed did I realize it was mania. Well, that & my mother/sister/father all having been diagnosed. And destroying my own stability that I usually depend on, even if it's a small factor. I haven't changed a lot since then, but I'm ruining my life a lot less now that I am self-aware. EDIT - Had some psychosis, but didn't realize that until I had a massive psychotic break after my awareness was already in place.
