In this case, it's definitely my own stubborn, mule-headedness. I've been sick now for four weeks. It's obviously a sinus infection based on the pain in my cheeks and forehead, the copious amounts of mucus, lack of a sore throat or cough, and this week has been particularly bad, with a sinus infection induced headache/migraine (also have all the other things like nausea) that will not go away despite maximum meds. I've got to go to the doctor, but I've been busy or had Rosie to tend to.
Well, Rosie's limping independently now and will spend this morning with her grandma while I give a final exam. There's no excuse for me not to drive directly to the walk-in clinic as soon as the final is over, except my own stubborn-headedness.
I plan to go; I just don't want to. Sigh.
