I'm not sure what the infected eye stuff is like as have only ever used cream from docs for conjunctivitis, but if it saves you a trip to a germ ridden docs surgery give it a go! If you have any probs though, please go to docs, you dont want to mess around with your eyes.
I think you'll be OK to go to college-it's not like you'll be shring towels with anyone will it and if you keep hygeinc and dont fiddle with your eyes I cant see you infecting anyone else.How horrible though for you-hope it clears up soon. :o)
