What did I do so wrong???

I'm struggling to feel well this winter. First off, I had my cold sore making me feel run down...

... And now, I have some sort of winter allergy and can't stop damn sneezing along with my chest filling up with gunk to make it harder for me to breathe. I woke in the night to a blocked nose for a short while, but that cleared up in short order and is gone now.
