Am i allergic to skittles?

in school we got these skittles, and i ate them. a minute later, my eyes were waiting, and i had a hard time breathing. when all the skittles were away from me, i was soon fine. but then on the bus some kids had them a few seats back. the same thing happened but not quite as bad. i think it's because i was not eating them. but i was thinking and well, i thought that's maybe it's the company. all candy they make i might be allergic too. could i have become allergic to them?
