Meltdowns feel like a kettle boiling over.
They feel like anger, impatience, sensory intolerance, overwhelm, etc.
You try to restrain yourself from exploding but you can't.
They involve a lot of adrenaline for fight / flight.
I'm about to have one myself because someone keeps opening and shutting a door.
I'm going to snappppp.
Shutdowns feel like you want to vanish.
Your surroundings fade or blur away because you can't deal with them.
You shut off your nervous system so you won't get any more input.
Sometimes stimming helps to regulate your nerves.
