That‘s why we have so many late diagnosed. People who are on the spectrum but were able to mask or were just lucky until luck runs out. Then it becomes a problem and a diagnosis. I knew I am different as long as I can remember. It was obvious in Kindergarten and also in every type of school and later in work. I‘m an old millennial and nobody was trained back then in the 80/90s. Before it became a diagnosis and before awareness started to rise, people unalived them, died homeless or in prisons/wards.
