If you are one of the lucky ones then your negative symptoms will go away when psychosis and depression ends. But for a very large percentage this doesn’t happen. Professionals distinguish between primary and secondary negative symptoms, where primary symptoms are due to the illness itself and secondary are due to other symptoms like psychosis or depression. I have strong avolition (powerty of will) and it’s a primary negative symptom. This means, for me personally, that every day, all day, I am more tired than normal people are after coming home from an 8 hour shift. I know this because there was a time before I got ill when I could work 8 hour shifts. I do get some chores done but it takes all my spare energy and it’s not enough to keep my apartment clean. I will try working maybe half a day a week soon, and I hope I can manage it, but I doubt I will ever be able to work more than 8 hours a week. I hope I am wrong, but I doubt it. And it has taken me years to get this far.
Edit: Actually avolition means you have a hard time doing what you want to do (i.e. willing things). I call my tiredness avolition too since they go hand in hand. Technically it might be wrong though, just so you know. And I also have a hard time doing what I want to do. Especially when tired.
Wikipedia explains it a lot better: “Avolition, as a symptom of various forms of psychopathology, is the decrease in the motivation to initiate and perform self-directed purposeful activities. Such activities that appear to be neglected usually include routine activities, including hobbies, going to work and/or school, and most notably, engaging in social activities. A person experiencing avolition may stay at home for long periods of time, rather than seeking out work or peer relations.”
