In a certain way having an alter is helpful, in the sense that there are two of us protecting the system. Intuition is deeper and more acute.
The most difficult aspects for me are when I dream of being split apart (it's confusing and frightening). The other, most challenging aspect of DID is the actual moment of dissociation. At that time I feel disoriented and have a sense of being "drunk", I guess is one way to put it. The sensation in my mind and body is very unpleasant, and lasts until I sleep it off.
