People call me anorexic but I've binged twice today?

Well, everyone's always saying I undereat and I'm anorexic, because I 'obsess' over my body image, check the calories of everything before I eat it, and usually skip lunch and dinner. But at about 12pm today I binged. I had... a bowl of wheatabix, a bowl of special K, tuna pasta, a tuna sandwhich, a piece of bread and er, and a lot more which I can't remember. I felt really bad, so I purged. Then again at half nine-ish, I had nine, yes, NINE chewy marshmallow bars, 3 bags of potato chips, 2 bowls of Wheetabix, a bowl of Special K , and a cup of full fat milk . I tried to purge again, but couldn't, so I cried for like an hour! What's wrong with me?!
