Are There Any Books Where the Male Protagonist Is Sick, Like Autism or Something?

I want to read a book similar to "When you are paranoid, your beloved wife is reborn to love you". The male protagonist has some kind of paranoia, autism, etc. But only the female protagonist can cure the male protagonist, and the male protagonist must be a female protagonist. Don't be abusive. I don't like abuse.
