i have a serious mental condition that makes losing weight impossibly hard and its related to anxiety (pls dont tell me to lose weight because i physically cant, i tried)

when i eat food, it tends to get messy fast, food goes on my shirt, on my face and in between the folds in the area, stuff like oil, sauce and crumbs get everywhere like behind my elbow, inside my chin, on my shirt and sometimes between my belly folds, its really painful and hard to clean up afterwards, i usually also smell much worse and people also look at me with strange looks and not only that but its also quite exhausting cuz the fat folds are in a lot of places you wouldnt think about (i have a small one on my forearms for example) and some are much harder to reach and dig into

one time i found a fry inside my chin fat and a woman smirked, i felt really embarrassed
