Why do I keep getting sick?

I think this has been the worse year for me health wise. As we all know being teachers, I'm exposed to a lot of germs throughout the day. I've had one skin infection, two colds, an ear infection, and food poisoning since September! Three of those have occurred since I started exercises and counting calories at the start of January. I know exercise and eating well is supposed to HELP your immune system, but does anyone else find that it puts your body into shock and actually makes you susceptible to illnesses? I'm not sure if it's my new regimen (I'm not crazily exercises or being extreme with my calories), just bad luck, or just the fact that I have gained a significant amount of weight in the past 2.5 years since my daughter was born. Thoughts?
