Crazy thoughts

For the past week, my head has been filled with a particular brand of crazy: grad school. I'm thinking of going back. I don't know when, but I'm thinking about it. I'm doing a mental pros and cons list. A PhD. Do I need one? Not really. Do I want one? I think so. I don't know. Yes. Maybe. Ummm, I don't know. You know what gives me pause? Having to take the GRE again if I don't apply this year. My scores are good for five years. They'll be toast by this coming February. I have such awful test anxiety. I dealt with more stress over the GRE than I did while writing my thesis. My scores are not great, though. I wonder if I should take it over again so that I have a better chance of getting into a doctoral program. What to do?
