High functioning? It depends:

I recently saw this cartoon https://the-art-of-autism.com/wp-content/uploads/2017/11/UnderstandtheSpectrum.pdf by Rebecca Burgess from The Art Of Autism website showing what often happens to so-called “high functioning” autistic people, who look “normal” to others’ eyes who see them as “not very autistic”. It shows how they can therefore be overloaded by others’ expectations and criticized for not meeting them in the expected ways, until they are overwhelmed and then people suddenly think “Whoa, you’re more autistic than I thought” and that they’re not actually capable of much after all. Autism is a spectrum and not a scale from high to low. Please click the link to see the entire cartoon.
