I rock but I am autistic. I do it more when I am anxious. Sometimes I just do it a little bit and other times people do notice. I also do weird things with my hands and have to keep on moving. I am seeing a new psychologist tomorrow and am scared to death. I am scared that she will say I am NOT autistic (I am far less autistic than when I was a child) or think I am doing everything for attention. I've had idiots who thought this. I just smile too much.
