I have DID and have all kinds of alters 103 to be exact and some are angry memory containing ones, some are sad some are happy, some suicidal, some.. you name it. no matter what the emotion or or memory there is one that matches it. I can't access any of them. What happens is that my therapist and I are talking and if I start feeling anything - angry, happy, sad whatever I switch into an alter. One second I am there talking and the next the session is over and Im somewhere else - the store, college, whatever and time has passed sometimes hours sometimes days and weeks. My therapist says this happens because those memories are the traumatic ones that were separated out of my awareness and as I gain experience with grounding and relaxing I will be able to remain aware and start remembering what those memories that are my alters are. We are doing things like playing with playdough and my telling my therapist how it looks, feels, smells, eating all kinds of strong smelling fruits and such... anything that will make my senses stay connected with the here and now while we are talking. Maybe you and your therapist can stop worrying about digging right in to those angry memories of yours and work on things like gaining experience with grounding and relaxing/self nurturing stuff so that you wont have this problem later on when its time again to try and find those angry memories.
