toxic past

my ex gave me depression and eating disorder. he always makes me feel i am the bad guy because i always want to confront misunderstanding (i can't help it, we need to resolve it duh). Then always talks abt how im gaining weight and being more fat that every time i eat i can hear his words (it still haunts me gosh). I was diagnose with anorexia after losing 17kg that worried my parents and after undergoing to medication and breaking up to that douchebag, im starting anew although that experiences haunts me 'till now that i can' t easily get over from it.
