Back to real medicine... and studying?

It took a month of psychiatry to convince me to hit the books. Or maybe it was the realization that I would be facing the most important exam of my life in 5 months time. Or maybe it is the thought of being employed in a year and a half with the job description involving saving lives in anything but fine print.
I don't know if I'm more worried about the exams themselves. I don't think so. It feels different. I think I'm terrified that my meagre knowledge of medicine would be insufficient to pull me through fourth year, let alone sustain a career in medicine.

The realization felt like a slap across my face. Maybe that's what I needed to hit the books again.

I feel 10 years older.
