Anorexia Recovery & Treatment

my parents still dont know.
i developed bulimia nervosa six months ago. i was bulimic for about 4 and a half months, no recovery, no telling parents, just stopped on my own.
i constantly am starting to think about my weight, im making meal plans thinspiration. i didnt eat at all one day and then i had 180 calories in 2 days.
my calorie goal tomorrow is 520.
i purged today and yesterday.
i excersise everyday, i want to starve myself and im terrified of gaining weight. but deep down, i feel like i want attention of some kind.
