Disability can definitely be frustrating.
My disabilities are from other things and I do not know Schizophrenia/schizoaffective from personal experience, only from a neighbor at a previous residence who was dealing with that.
There would be occasions where they would say, "It is another one of those times where I'm going to need to stay in for a couple days."
Details weren't offered and I didn't ask.
