Do I have an eating disorder?

Hi! Im 13, 5'8 and i am 116 lbs. I am really tall and skinny. I have a problem though: i eat when im bored. I cant help it. I eat little snacks threw out the day and i dont gain a pound. Im stick thin (but my legs and muscly enough from playing soccer so my legs dont look like sticks) ANYWAYS, ia that an eating Disorder? Like i wasnt hungry at all and i juat ate a bowl of cereal. I get hungry fast though. I dont gain a pound. I guess i have a very fast matabolism. Anyways, do i have an eating disorder? How can i stop doing this? And i excersice ALOT btw.
