Do I have an eating disorder? I so which one, bulimia or anorexia?

In January (or around then) a few people told me that i was looking rather skinny. In my mind I was like how, because i had not lost any weight. I liked the attention, so I tried doing things to lose weight. For a while I basically just stayed the same weight. Then I got sick for three days and lost like 7 pounds. The comments came flowing in again. I kept my weight down like that until like April. Then at the beginning of may I had a dance show and I felt not skinny enough, so I tried throwing up after i ate. I did that until about a week ago. Then someone had confronted me and accused me of an eating disorder. I denied it and ate normal for a week. This week I haven't been eating that much and when I do eat anything, even just a bowl of cereal, I throw it up. I hate the way I look and cry so much about it. I have thoughts about not eating for a week, but my mom would notice. So does this sound like anorexia or bulimia, or both??? I always compare the way I look to others around me. I research the topic so much. I wear big clothes and people have been telling me I look so tired lately. I just need to know. Also this is bad, but I don't want to get better until I am really skinny!
