Autism: Overstimulated

I made this vlog while overstimulated so you can see the difference in my demeanor when compared to other videos. I act and sound very angry and it makes people ask me what I'm so mad about or if I have an attitude problem. It will piss me off if I get treated like I'm choosing to act and sound like this. I'm not, I have zero control of my tone of voice when I'm overstimulated. It's one of the first things to noticeably change.
I got overstimulated because I was transitioning between mom's car and home when mom wanted me to do something that required brainpower while I was still switching gears between "car" and "home". I ended up yelling at her a bit.
But there you go, this is how I look and talk when I'm overstimulated. This is the point where I'll be seeking somewhere quiet to chill out and let me regain some sense of "I can control my environment", because I can get overstimulated when I feel I have zero control of the stimuli coming at me.
I have little "zones" to describe where I'm at in terms of stimulation levels:
-Green zone = Calm and cool, everything's fine. All control rods are in place and I'm having a great time.
-Yellow zone = Uh oh, I'm starting to lose my cool and I'm not calm. The control rods aren't descending fast enough to control the reactions going on inside me.
-Low red zone = A meltdown is imminent if I don't take drastic action to get somewhere quiet where I feel in control.
-High red zone = Meltdown.
You actually see me calm down right before your eyes towards the end of the video because my brain wasn't flailing at me to "get control of something!" See how fast the calming can happen if you let an autistic person take some time to calm down? Sometimes all we need is somewhere quiet where we can feel in control of the stimuli coming at us.
So many people out there keep pushing an autistic person by wrenching more control away from them when they go into the meltdown redzone, and then they blame the autistic person for having a meltdown. Don't be one of those people, okay?
