I think that is so cool that you are strong enough to have that much control over what your alters do when. keep up the great work.

Before I was integrated I had no control over who came out or even when the alters could come out. they all had their own jobs, purposes, reasons for being...

for example

if I was having a stressful day those alters who's job, purpose reason for being was to handle times when I could not handle stress, took over. I would later become aware to find what ever was stressing me out was taken care of.

if something triggered me into being angry, the alter who's job. purpose reason for being was to contain and deal with situations that caused the anger would take over and contain and deal with that event that caused me to feel angry.

if i was in an intimate moment or a situation that led to sex which ever sexualized alter who's job it was to contain/hold/ deal with that sex act or sexual situation took control and did their job/purpose/reason for being.

if I was home watching tv and something on the show or movie I was watching triggered me which ever alter who's job/purpose/reason for being was to contain/hold/deal with that issue took over control..

the list goes on and on. being DID and switching into alters was something that happened to me, not something I could control.. i couldn't think or say something like "I will only switch alters when I am with my therapist" or I will only switch into alters when I am alone" or what ever/who ever and where ever.

one time I got so frustrated during therapy because I could not control the who, what where and when I dissociated (your words switching) and I was having one of those weeks where it seemed like every time I turned around I was finding I had done /said or met with friends and didnt remember doing so. My therapist explained to me that if I had the control to choose then my problem would have been called "selective amnesia" not "dissociative amnesia" and I would not have been diagnosed with DID because the diagnostics stated the words "recurrently take control.." it didnt say "host recurrently gives control..." after that I settled down and stopped focusing on that fact that I didnt have control and got to work on things like grounding and taking care of those things that caused me to dissociate.

As I became stronger with learning how to handle my problems the alters learned their jobs/purposes/reasons for being was no longer needed so they merged with me to where we are now...one whole person.
