I got my diagnosis as a teenager. I am now in my 30s. To this day I continue to have realizations about how I’m not actually just a lazier piece of crap than everyone else around me.
My shrink told me he regularly has middle age people break down and start crying when they get their diagnosis. I guess thinking you're a lazy piece of shit your whole life has a bit of a negative emotional impact, lol.
I was lucky enough to have a Mother who was aware enough to get me a diagnosis when I was 10. My dad still no matter what thinks im lazy and what didnt work for him should magically work for me.
