Amnicr.
I am sorry that you ended up in the ER last night...but it sounds like you got some helpful information that should put your mind at ease...great news that your cardio function looks good!
I am certain that your other results will show healthy finding as well...and at that point, you can start to focus your efforts on anxiety management.
We are here to support and cheer you on, so keep posting.:)

HAPPY BIRTHDAY!!!!!!!!!!!!!!!!!!!!!
