I have sensory processing disorder but it never gets this bad for me, for me I get extremely irritable and angry and can break down crying if I gets to bad.

I read somewhere that you can set limits for the thing that triggers sensory overload. But it is true that sensory overload doesn't just come from autism it can come from ADHD, GAD, PTSD, and a couple others
