Third one of the month

Is it even possible that I have yet another infection?!?!? This one isn't contagious because it's a viral infection. My doctor told me that usually only chilren get it. I rolled my eyes in exasperation. When will this madness end? I just don't want to be infected with anything anymore!!!! Leave me alone! It's been a battle all April...me against bacteria and viruses, and I've lost every time. Craziness.
