Well, this delusion of theirs has solved at least one problem for me. I have a battery of psych tests coming up on the eighteenth of this month. For months I have been telling them that I can't answer too many of the questions on these tests - my brain doesn't process information the same as other people and many of the questions are simply nonsensical to me.

However, I have an alter who can answer them without difficulties. Since she is a delusion (according to them), then she is all in my head. If she is all in my head, then I'm just going to have her take the tests. They're in for a surprise.
