I've always been this way, even as a child, I was extreme and volatile, not unruley and undisciplined (quite the opposite actually) but my behaviour was noticeably different. Now idk if that's a sign of being symptomatic or not, but you get the idea as a teen it became painfully clear just HOW different, and that's when I decided my brain was just wired differently,and I had to find ways to work around it to deal with life and school in order to cope and that's how I still view it today, it just has an official name now
