The doc said my symptoms could just be stress related, but they could also be indicative of Grave's Disease, especially given the lab results I had five months ago. I'll have better information sometime before next week, depending on how fast the lab turnaround is. Next week I have an appointment to get my thyroid gland ultrasounded, just in case.
After the doctor visit I felt a need to escape from the world so I drove the van to Big Basin and got a camping spot, and walked around in the light rain, enjoying the relative quiet of the forest. There is no cell coverage anywhere within the park, so I was a bit isolated, but that was just fine. I think I should do that sort of thing more often, in fact.
