I already read of some your blogs and I think I commented on one a while back. I'm following for sure and added you to my ginabot. Yes, I agree with the things you've added... haha. I think in a way that "preferred interest" becomes at some point, rabid insatiable curiosity (with whatever is in front of me.)
Not sure I suffer enough with not giving a fuck. I WISH! Then again, I'm tuned out a lot. Or tuned into whatever I'm not supposed to be. Except for my kids. We get each other.
Maybe that's my method. My youngest son whose IQ is 136, he's psychopathic levels of stoic. My daughter, she cares about everything but can't exactly relate to why she does, do she meltsdown. Ha!
My biggest problem is identifying with late diagnoses and diagnosis in general. I probably will never formally or properly identify with HFASD. I'm so stuck in my former identity. I've already found labels for all the randomness I am. I struggle often with US/THEY, WE/THEM. Maybe that is a good topic for discussion: late diagnosis identity.
