Stress, anxiety levels, and sensory overload can all make my autistic traits pop out. The best example I can give is when I go into an electronics parts supply store, it can throw me into an sensory overload condition. Electronics is one of my special interests, and I kick into full think tank mode of all the different projects I can do with all of the parts in the store. Normally I have very little problems looking people in the eyes, but when my mind fills up and overloads with all the thoughts regarding all the projects I could do, it becomes painful to look the store clerk in the eyes, conversation becomes extremely difficult, I become more sensitive to light, and so on. Give me a few minutes outside of the store, let my mind clear of all the little projects I was thinking of, and I return to normal.
