My own DID stems from satantic ritual abuse when i was a child. As with any DID, there is alot of deprogramming that is involved, because it all stems from abuse. It is perfectly logical, all the anger, rage, feelings of wanting to do this or that.
For myself when a part comes up like this i love on them, and go the way of acceptance, yet educating them. For instance i know that unforgiveness only hurts the one, that is the one, that is holding the unforgiveness. When i decided to forgive my step-mother i actually threw up all this bitterness that i had been holding n. It was such a relief! I think forgiveness is such a bottom floor need with all parts of me, and as they have we all feel better.
Sometimes we have to start with acceptance of feeling that way, nurturing, loving and encouraging. There can b layers of rage built up, anger and hurt. At one point i had a punching bag n my apt. and i remember hitting and hitting it. When i stopped, i sat down kinda out of breath and up comes to my memory something that happened long long long ago, that i had forgotten all about. Of course so much of what has come up has been stuff that i was totally disconnected from n the first place. I encourage u too let this part come out and express and work out their anger n some kind of physical way, until it is just that, worked, sweated, cried, and given enough support and validation 2 b worked out. There also may need to b boundaries that need to b set.
I have also found with myself that it has been helpful to do inner mind work, such as i will say for example. " I speak to my mind and open every file of hate, every file of abuse, and i pull down and off of my mind any programming that has taken place and decree that it is null and void." For me it has been very helpful.
Anyway, bless u and hear and know that we accept u.
