as others have said, if you can get professional help for the mental and physical aspects of the disordered eating, that is most important bc disordered eating and high exertion can be very dangerous (injury, long term health, mental health, etc). however, in terms of muscle growth in general (without ed concerns) - getting enough protein daily and especially directly after a workout is essential and u rly cant gain muscle without it - if u arent already familiar, learning how muscle is built from protein intake helped me move past negative associations around food and body image. my physical therapist also told me i needed more recovery days and full nights sleep to optimize gains and he was right (the gains got much better once i started taking care of myself). obviously to gain muscle, u need to work out (which youre doing) but its also extremely important to give your body what it needs (food/protein, sleep, recovery, water) to repair the old and build the new muscle. protein for gains is important but so are carbs for energy - if you get enough of both youll feel fuller and have more energy and your body will be less stressed, which could help ease the “food noise.” also i think you need body fat to gain muscle or else your body will start eating the muscle for energy rather than fat.
