The overwhelming feelings are very hard to take in the beginning. But over time it gets better. I found out in the beginning of April that I need to fix my life long BAV and now a ascending aortic anerysium (just like you). I struggled with which valve to get but have decided on a tissue valve. After that I am sick of the wait and find the anticipation is no fun......so I have to hurry up and wait (as Adam's wife said). :0) Surgery is next week, the 21.
I wish you positive thoughts and a speedy recovery!
