Hi Skeezks. This problem came on while I was in therapy for PTSD. Right now my medication for depression and PTSD is keeping it pretty well at bay but I never know when it will happen again. It comes out of the blue at times. I thought it was a tic. I have had so much shame about it. People have laughed at me, too. I don't know how to let go of the shame and worry. I'm not in counseling right now. I would like to let go of all of this shame and worry that's for sure. Thanks for your post.
