Advice on how to stop emotional eating and food obsession when depressed?

Honey, this isn't something you can fix on your own. There's a reason you're doing this to yourself, and it has to do with fear, self-esteem and control. Please seek out help from a counselor qualified to help you overcome your eating disorder. Otherwise eventually your body will rebel against the abuse you're inflicting, and you won't be able to keep anything down. Your gag reflex will become automatic and you'll throw up even the food you want to keep down. And sooner or later the vomit will eat away at your throat and esophagus, and you may not be able to swallow. I don't mean to be an alarmist, but the fact that the blood vessels in your eyes are bursting is a sure sign that your body is suffering. Please, please get help right away. There's no shame in asking, and the therapist can also talk to your parents. This isn't a trust issue, and you didn't do anything to them. You're fighting a battle against your own body, and you need all the support you can get.
