Health update
Woot. So my GP talked to my cardiologist and it looks like I won't need surgery. XD The current plan is to wait a year and then get another echo and see how it looks. I have an appointment on Thursday with a heart surgeon to confirm, during which I plan ask just what the mass is made out of. Still though, good news!
They drew some more blood to test my white blood count again and to check on my thyroid (which was slightly enlarged) but there's no reason to expect that to turn out to be anything.
All in all, yay!
Thanks for all the wonderful support and kind words. :)
