Dear ...
An eating disorder is a psychiatric illness. You need to seek help from a mental health professional. Bariatric surgery may be considered in addition to counseling, but I would recommend you consult with a mental health professional (ideally a psychiatrist) to address what is driving this self destructive behavior. Eating disorders are increasingly found in young women and men, and they can destroy your health. Treat this as any other disease, there is nothing to be ashamed of. Best wishes
