Don't listen to him! You stay your healthy happy self! Some people (even though he is your father) just say things to be mean, maybe his idea of healthy is stick skinny many people have different ideas of whats a healthy weight, but listen to your doctors, they know better about your body then your dad, and not meaning to be mean but maybe your father has his own issues, because thats not something he should be saying to his daughter, don't let him bring you down please, being bulimic is not healthy! Its better to be a little over weight then be way too skinny you hear me!? Keep your chin up, and about your cat issue, maybe just after your dad leaves take the food from your cat, to stay away from any further arguments with your father :)
