Autistic Hedgehog

I've gone into catatonia-like states during my most extreme meltdowns. My body will go completely rigid, and if I try to speak, it will come out as squeaks or strange growls. In most, I tend to have trouble speaking but can generally move around. And in others, I yell and punch holes in walls. These are caused by prolonged exposure to triggers or stress that I'm not able to get away from (like noises or money stress). Depression and anxiety certainly do not help.
