The good news is that my heart is okay. The cardiologist did an echo and everything looks well within normal, so that rules out nearly all of the scary stuff. People have been on my case for not being more aggressive with the emergency room. The woman who did my echo was appalled that they didn't do an EKG immediately.
The problem is, I had chest pressure. It was 3am. I was having trouble breathing. And, most importantly, it wasn't my job to know how serious those symptoms were, it was the doctors'. While I understand that they were being useless, leaving it up to me, it was more than I could do that day.
I deleted a few comments on the above post because they either had more personal info than I wanted about me on the internet or because I sounded too cranky. Stuff always sounds harsher in writing. Suffice it to say, I've felt *thoroughly* fed up an exhausted this week. It's been hard to stay motivated, but I try not to be too hard on myself. In two months I won't have the luxury of being able to slack off for a week :-).
