accused of having an eating disorder?

 My grandmother just accused me of haveing anorexia and if theres one thing i know i do not whatsoever have an eating disorder and i am not in denile right now.Im not eating suuuuure because im not hungry can’t people understand that i mean i know your worried because i almost passed out on the street today but that’s not because im not eating i mean i was HOT today and i also have a throat infection and stuff like that and then i ad like 2 sweaters on cuz my grandma thought it was gonna be cold.Honestly eating disorders is a confusing topic with an eating disorder you starve yourself because in the mirror you see that  your fat wich proves that you can’t really depend on your head to tell you what you look like because your head can fuck with you where it causes all of this crap on looking over weight or other stuff so it’s either i am a tiny over weight or m yheads playing games with me so maybe i do have an eating disorder and i just don’t know it i might be typing this now all because im in denial but honestly i don’t know if i am all i know is that there’s no poin in eating if im not hungry.
