I've struggled with the same thing dude, it's horrible. It screwed up my teeth and my throat, I still can't really eat properly and struggle to swallow anything. If I eat too much I have the urge to get it out because I feel awful. I also end up slipping into anaemia when I don't eat. Don't let it get any further than it has in you, force yourself to eat properly and keep it down. Get the help of a doctor if you have to.
