Ok so im not sure if anyone else has this or even heard of this but basically I have this thing that whenever I eat until I can't eat anymore for like a week straight i get anhedonia the next day and even after i start eating like a normal person the anhedonia lasts for like a month and all I can do is wait it out I tried everything exercise, sunlight, eating healthy, supplements, anything I can think of to speed up the process nothing is effective please if anyone knows tell me what to do speed up the process of getting better at first I thought not eating enough was my problem and now im stuck in this phase of anhdonia which rly sucks

I'm 5'11 and weigh 140lbs
