I am thirty years old, and am a fully functional Aspie with a family and a job. I deal with people and life fairly well. But I have noticed in the last few months, I seem to have developed a new stim. I have always rocked and jerked my foot (endlessly, generally as long as I'm sitting still. But now, when I am acutely stressed (someone asks me something and I can't form words, I lose my ipod, I am scared, my son, husband, and the dog are making noise all at once or trying to talk to me all at once) I open and close my hands rapidly, often with enough force to cut my nails into my palm if I don't trim them. I thought stims were programmed into the brain, and didn't know we could pick up new ones. Has anyone else had this happen?
