I feel that way too...in spite of medication, therapy, and working very hard. I have no advice, but you are NOT alone in this.Good Evening and welcome to the group!
Today I myself have been having one of those days, when I have been feeling cognitively overloaded.
I am feeling better now and it is coming up on Midnight here in Derry, New Hampshire where I live.
As I have been ageing, I have been becoming more stereotypically autistic.
It is like I am going backwards.
