[The First Aria]

All my lab work came back normal, so my spiro may not be to blame. Unfortunately, they dont know what is to blame for my heart issue.

But hey, there's a light at the end of the tunnel. My old boss called me asking me to come take my job back!

That's great news about labs & job (congrats), maybe check into panic attacks???. I'm glad you're ok, hang in there. 

Panic Attack

E2 has side effects- anxiety is one of them

I was wondering the same thing.  With everything going on, forget about the E, your job and family puts enough stuff on ya.....  Then add the E and it could be a powder keg with a lit fuse?
