You know what? We. Yes, "we" having seen others posts in this thread who's opinions make sense to us and our DID experiences based on our perceptions are a comfort from what was suggested earlier about our condition.
Having been comforted by the words of others who can and do switch volutarily at times has started to make us feel valid again and have a small sense of realism once again.
Just because some here can switch at will does not mean that they are not still subject to triggers.
We are such a being. We put up with triggers day in and day out but, when our host is worried he can ask a protector to take his place and deal with the situation at hand. D's protectors are caring and compassionate states or personas that will do anything for him.
One even took care of him for a full day when he needed to go to the local ER and was afraid to go on his own.
That is the love and dedication of a strong protector alter.
We have a witness who can back up the protector alter taking control.
Maybe your DSM-5 isn't as perfect as you believe it to be. I'm starting to feel myself again. Confidence in who I/We are is returning.
We are grateful for this thread. It has set our worries and fears at ease.
