that is pretty odd to have occurred as many times in one year as it has. i had pink eye once in my life and never since. it might have to do with washing necessary materials where your eye comes close or in contact with when you have pinkeye. i know i caught strep throat at college 3 times in one semester because i forgot to change my toothbrush once and didn't wash my sheets the second time so maybe close approximation to objects has been keeping the bacteria in close proximity to certain living spaces you reside often. xbox controllers and so on should be wiped down with clorox antibacterial wipes to disinfect any bacteria. hope this helps
pinkeye. i have gotten pinkeye 5 times in the last year and a half. before that i can't remember the last time i had it. it only occurs in my left eye and no one (i know) has ever gotten it from me. i've been to the doctor for it and they keep telling me its just pinkeye and its probably not bacterial and i'll be okay. but it keeps coming back and its really bothersome.
