Hi littlethistle....welcome to PC!
It took me awhile to figure out that the Others actually had their own thing going on....because their thoughts are not anything that I'm intentionally thinking about. Alters (if they be alters) don't just go away...they go silent.
The taking over the body for their personal use is kind of the biggest clue to me about alters because everyone looks at me weird when I tell them that because evidently singletons don't experience such things.
As far as working.....most everyone in our system understands the importance of working because it keeps us safe, housed, and fed. Our workers go to work doing whatever and the house mates do the home life.
Not being able to hold a job would then lend to this being a disorder because it's holding you back from a quality of living of self-sufficiency. I guess it can be considered a limitation to us because we can work....after all that's what is important to society is can you work...not draw or paint, read books.....can you work. I learned that one when denied for disability.
Anyways....I hope things get better for you, please tell us more.
