I swear, every time I catch the cold/flu I stay sick for at least a week and it's bad. It's the same virus going around. I don't understand why the people around me aren't get it as bad as me. Even if we're in the same house sharing the same air, I have it worst. I take good care of myself by getting plenty of sleep, drinking plenty of water, and eating super healthy. I just don't get it. Do I just have a weak immune system?
