It's great that you're getting some awareness of what works for you and what doesn't. I couldn't keep teaching--the environment was too overwhelming. I am not autistic but a Highly Sensitive Person (HSP is a personality trait of 15-20% of the population). We're on the opposite end of the scale to autism but very similar in overstimulation and sensitivity to noise etc. I also have an immune disorder, so becoming a writer and quitting teaching was the best thing I did for myself!
