Ah, Relief
So I went to the doctor about my heart issues yesterday. No conclusion has been drawn yet, really, because I have to track my BP over the next two months and get blood tests and all that fun stuff, but basically he thinks I'm fine. His reading of my BP was 120/80 or so, and while that's not as low as I'd like it's within the normal range. Verdict: the machines suck. It's possibly my thyroid is messing with my blood pressure, though. Whatever, I'm not about to die and that's the important thing.
