my guy couldn't deal with it either...
this may sound bad but it helped me and I'm not suggesting it, just telling you what happened. I went got a deep tissue massage and the woman put bruises on me. I wept, and went with the feelings and it sure seemed like memories were leaving my body. As I nursed the pain from the bruises for a few days I just sat in those feelings but some how I was reprogramming my brain and I have no idea how. It's just like it happened on it's own. So went back to that same massage therapist about 5 times. Each time I had similar response but not as strong. The final one I was like, whoa, this massage hurts you gotta go lighter, so the progression had gotten better. I know something got worked out in my brain from it. I told the MT don't worry about me sniffling and crying, I'm OK, I just had a bad day. So again this may be bad, I think it helped me. I haven't had that intense drive to be hit by my lover really in a long time.
Sorry you are failing at sitting with the feelings.
