Am i starting to become bulimic?

For the month of march, Either every other week or every week. I MAKE myself through up a couple times a week. Now before anyone asks, I do not wish to be skinny or think that's how i want to loose weight. If i wanted to lose weight id do it the right way, exercise and portion meals. It started in the beginning of this month. I would eat greasy foods a lot in school. For example, cheeseteaks, bacon, egg && cheese sandwich. But id order off the lunch trucks. && they have a greasy stove they cook it on. SO one day i began to get this burn in my throat. Like it hurt and burned, so usually in the past when id make myself throw it up, id feel better. Now the burn comes often and yesterday i did not eat mainly all day. I woke up i ate this pizza and you heat up in the microwave, when i went to school. I had me some coffee and bought a juice to go with it. When i was in cl, i got the feeling to throw up but also the burn in my throat, i tried making myself throw up but the rest rm was over crowded. I went home tried throwing up, a little came up. I left out and when i came back i felt sick i tried making myself and i threw up a little. I took a nap and woke up feeling so sick i tried throwing up. A little came out, so i was hungry and served myself some food. But when i sat down i looked at my meal(rice, chicken and a side of tomatoes) i just didn't want to eat it but i was hungry. So i tried eating a tomatoe and as soon as it went down i had a feeling of it coming up. This is when i started to feel really sick. i drank ginger ale and i had the burn in my throat and made myself throw it up. It was disgusting. i finally just got so depressed and scared that its becoming permanent. I called a nurse (after hour clinic) she told me to go to an emergency rm(planning an appt) i told her when i throw up i taste this nasty liquid like medicine sometimes and its yellow. she said she thinking its that im starting to make the liquid from my stomach come up. She also told me to get checked for open sores in my throat, the acid i throw up is whats making the burning. I know its my fault and i have a problem. I just HATE being sick so i make myself throw up to get red of the feeling...ANy words??? or advise??
