Another releae valve needs to be found. Even silly things can help distract the mind. Walking backwards on a treadmil, watch a video on youtube on how to juggle and try it, find a recipe and try to make it, take a red pen and slash red marks on your arm instead, get silly puddy and squish it in your hands. I am not sure how long you have been in therapy but you should have seen some relief by now. They should have addressed some of the root core as to why you turn everything onto yourself. EMDR has releases some frozen trauma for me which in return has made it easier to obstain from self harm.
