How can you explain what being autistic is like to someone that is not autistic? I’ve recently like in the past 6-8 months have discovered that I am autistic. I’ve been with my boyfriend for 5 1/2 years and can’t really explain it. I have never been good at communicating anything, especially emotions. Today I babysat my 6 month old nephew and have been feeling anxious and weird all day after. I’ve been feeling borderline overstimulated all day and I don’t know how to communicate that to someone that doesn’t understand.
