I'm only talking about myself, since I'm talking about what I can't deny rationally, i.e. the fact of my own conscious experience. I can't speak for schizophrenics. I don't think you need a definition for your self in the sense that I'm talking about. Like you said, how would such a definition work? Definitions aside, I can't deny the fact of that self, even though I could by a slim margin doubt literally anything else. I'm talking about the essential process of experiencing whatever comes to pass in my mind and senses. That process would surely continue if my memories disappeared. If all thoughts, memories and senses disappeared, well I can hardly say what would happen. All I can say for certain that my experience is happening right now, and it's not contingent on any particular thought, memory or sense.
