millies' Autistic Meltdown Phases chart
I, with the help of my Occupational Therapist, made this chart of symptoms I experience during an autistic shutdown.
It's specific to my experience, but you can use it if it's useful for you. I plan to update in the future if I have more or better descriptions of how it feels for me.

This was referenced in my latest video on YouTube which you can watch here:
