Help :(

I got new glasses about two weeks ago. For the past 7 days, I've had a nasty headache that I just can't kill. It could be a variety of things: weather changes, PMS, new glasses, stress or anything really. I honestly think, for the most part, that it's from my glasses. I took Adam to Chik-Fil-A yesterday while he was at Chocolate Fest, and I couldn't read the prices and unit counts of the value meals on their board from about 15 feet away. Well, at least I know my glasses are fuxored. On the other hand, my headache just isn't getting better. I'm starting to become sensitive to light now, and I have to leave for class at 9. I've already missed most of my classes twice due to finding out about Adam's Mom and the nasty rain that hit Indy a few weeks ago. The rain reason may seem like a lame excuse, but I literally looked like I had jumped into a pool with my clothes and backpack on. I had two classes left to be squishy, cold, and wet. So, that's my reasoning for that. I really don't want to miss school, but I really don't want to aggravate this headache, either. oiiiiiiii. If I do miss school today, I'll at the very least go get my prescription changed. I just don't know what to do.
