I think its normal....I get a bit more anxious around my dr. appointments and whether there's been any further changes to my condition. And I'm sure I will be anxious when the big day arrives...But everyone's situation can be different. I've been in the waiting room for 5 months. For me, it got a bit easier when it sunk in and I accepted my situation, decided to face it head on and lay out some steps I would take to try and prepare for the eventful day (which for me is still to come as well - I'm 47, have a severe regurg and my left ventricle started dilating. My surgery is expected to be late summer). I have read some good books on the lead up to, and recovery from, open heart surgery. I'm educating myself and reading up on the procedure (to the extent I'm comfortable with it) so that I know what to ask/what to expect, exercising daily (ever tried yoga?), eating well, getting rest and getting reassurance through great forums like this. I also have a friend who went through this, so that is a helpful resource. My cardiologist and surgeon have also been very reassuring. I keep telling myself it will be much better once this is behind me. I also try to keep it in perspective...my wife and I have 3 friends all battling cancer (one terminal with 2 young boys) and my wife's mother just passed away...its been a tough year, but better days are ahead. Hang in there and remember you are in good hands with the doctors etc.
