This is an interesting link for trauma release exercises. The body memories you are experiencing happen to alot of us. The idea is that the body remembers trauma because at the exact time of injury the brain cannot process the overload of incoming senses. I found this helpful for me. I think you described it so well. About how the laughter is so strange but it comes out anyway (I use scarcasim to hide the hurt also).
If you would like (((safe hug))) or not (((no hug))) whichever is best for you.
