 some people even have specific stems for specific emotions. For example, I flap my hands whenever I'm happy or excited. I twirl the right side of my hair whenever I'm anxious about something. If I'm on the edge of a panic attack, I will either bounce my right leg, pace back and forth, or repeat certain phrases to myself until I calm down. A lot of times, I won't even notice that I'm doing these things until they're pointed out to me. The reason why I stopped is because of the social aspects of school, you know, like people looking at you, drawing attention to yourself.
