in my location when a treatment provider or anyone else says the whole system is under threat it means something has triggered the switching...

kind of like (using a completely normal and natural situation anyone male female, mental disordered or not is taught in school) if you are walking down a street and see someone across the road you may think about how dangerous it is to be out walking after dark and what can happen. you may think that person is a threat or danger to you.

well in my location it is believed that dissociation is a reaction to a trigger... something happens to cause the one in control (host or alter) to dissociate. the act of dissociating causes the switching from one to another.

so before I was integrated, when my treatment providers would say to me something like it seems that my whole system is under threat I sit down and try to work out what is happening that is out of the ordinary\triggering the switching rapidly from one to the other.

my suggestion take time to breath and think about what things may be triggering you to dissociate. triggers can be anything positive or negative. its what ever is something you or the one in control can not handle at that moment so they had to switch to someone else who could.
