My stimming story is a little different from other people’s stimming stories. My initial stim was a monotone hum. Unfortunately, that was an unacceptable one. My mother asked what it was for. I said it was to get rid of excess energy. Eventually, my mother would tell me to go run up and down the hall. (We had a long hallway in our house.) I found better ways to stim as a person throughout my life, even when I was not allowed to stim by my sisters. (I was also not allowed to enjoy my own money or mental safety.) Of course, once I got away from my sisters, I was “allowed” to stim again. Strangely enough, I did not stim too much.
There are many times and ways I stim, but one thing they have in common: they are to get rid of excess emotional energy. That means, stimming can come at any time, for any reason. It’s a comfort that many neurotypicals do not understand or apparently need, so they always want us to not do it. They don’t want any indication that we are autistic. I say, screw them.
