Thank you all for answering, it means a lot to me! I have an appointment with a regular psychologist on monday and I will ask her what she thinks. The thing is that the symptoms come and go and I can have days without them and then days with them so it is weird. It is a new symptom development which makes me connect it to anxiety and stress but when one has pcs there is no telling to where the symptoms really stem from I guess. It is very frightening to look at your sister and see another person for a second before her face kind of morphs into the one I recognize.. I am also kind of in a huge crisis in my life right now and maybe I am under more stress than I would like to admit to myself, dealing with childhood and family issues maybe brought this dissociation on..hmm..
