I have read online that autistic meltdowns last 'from minutes to over an hour'. Mine certainly don't, they last from seconds up to a minute or so. They tend to be somewhat violent - always self-directed - and the trigger is often something apparently very minor. They only happen, or I allow them to happen, if I am alone. If I am with others, I tend to shut down instead, also of short duration. I wondered if anyone else had these sort of short-duration episodes, and if they, like me, do not have anything that lasts longer than a minute or so?
