try to do a maintenance phase and eat intuitively for a while. dont count calories. eat when youre hungry and try to make sure its healthy but dont think too much about it. for example i had cereal (cuz its delicious) and then fruit on the side for health lol. its never that serious enough to make you feel awful. maybe take a week off from the gym to rest and treat yourself and start back up slowly. youve got this! youre not gonna gain all your weight back instantly
