There is an author that wrote a book on did, im not too familiar of who she is or anything but i stumbled across her youtube video where she talked about a part that was violent, si and wanted to kill her. Her t told her to try showing gratitude with that part. It was the parts job to shut everything down if it got to be too much. The part had been there through all of the pain carrying the burdens and was only doing its job. That the part like the rest was tghere to help even if it didnt appear that way. Once she was able to be thankful for that part, things immediately got better and within a week that part was integrated. I dont know if that works in every case but remember, they are there to help you, their sole purpose is to help, even if they have less conventional ways of doing so.

I hope you find help in this. Wishing you all the best
