I struggle with chronic anhedonia and it has lasted for over a year and a half now. But I have come up with a theory that might get rid of it for me and everyone else who struggles with it right here and now. I don't know if this will work or not, but with anhedonia, you have a chronically overly active part of the brain (the hpa axis which is the area of the brain responsible for the stress response) while another area of the brain turns off which is the area responsible for feelings of pleasure (our good moods). If you can make yourself pass out, then that overly active part of the brain might turn off and allow your feelings of pleasure to turn back on. The brain has to devote all its function to vital organs and such to keep them alive while you are passed out. So this would have to mean that the overly active part of the brain I mentioned would have to turn off. So when you wake back up, you might have your full feelings of pleasure back to you and no more anhedonia. Being aware of stress (both consciously and subconsciously) also causes that stress region of the brain to become overly active as well. When it is overly active and can't be regulated, that is why the area responsible for pleasure turns off. So by making yourself pass out in this situation as well, then you would have temporarily gotten rid of all conscious and subconscious awareness of that stress which would turn off the stress response. Awareness of stressful life events=overly active stress response. Absence of awareness=no stress response. So if you can also wake back up having amnesia, then that stress response would also be turned off for the time being and further give your brain the chance to regulate itself and turn its feelings of pleasure back on. This whole thing is just a theory of mine. I don't know if it will work or not. I'm not sure if I should recommend others trying it and reporting back to me to see if it worked for them or not. If it works for them, then I am going to try it. I also thought of being put out by anesthesia which would of been a better alternative to passing out since anesthesia puts you out longer. But since I don't have that option, then making myself pass out would be the only option here. There is a way to do it. I heard that you have to hyperventilate and stand up.
