Why am I taking APs?

Okay, so I have come to the realization that I only have 14 days left before my first AP and I am screwed. I keep missing classes because of doctor appointments, I am so tired because of  taking Gabapentin and I don't see how I will possibly be able to manage a 4 let alone a 5 on any of my exams. This sucks. My stress levels are above what is medically safe.
