question: I am F. 23. History of mental health, Dx BPD and dissociative disorder. Meds for MH only propranolol. Lately I keep jerking and waving, shaking, repetitively moving my hand over and over again, like a snappy crocodile. Sometimes it is in a rhythm, sometimes random, sometimes I do not even realise I am doing it until it is pointed out. It happens most when I am stressed out. I feel very strange. I feel unable to control my body sometimes and do a skip or my body just moves for me without me telling it to. Is that anxiety related? So I know what skills to try and use or look up please. Thank you.
