Schizoaffective disorder is a terrifying and a lonely illness, so I hope that your friend doesn't suffer too much — my heart goes out to them. I have my wife to help me when I need her, but I have otherwise chosen to isolate myself and handle it on my own. I take my meds, I take care of my mind and body, and I attend therapy to get the tools I need. I have always fought my own battles and I don't think anyone can actually help me, nor could I ever bring myself to put that burden on anyone. I have my journal, the gym, my running shoes, and my workshop, plenty of healthy ways to get help without burdening anyone who doesn't know what they're signing up for.
