It turns out, of course, that nothing is wrong, thankfully. They just called to tell me my results came back normal. Which, to me, seems like the sort of message that can be left on one's answering machine: "Hi Rhiannon, this is the Health Centre calling to tell you your test results are back and everything is A-OK." And thusly save everyone involved a lot of worry.
It's been a fairly mundane few days other than that, I've mostly been busy writing essays and such. I'm getting really excited for Halloween. I'm also finely feeling better from that evil cold, which is greatly, greatly relieving.
