Hi there! I'm just over 4 months post op. I had the same emotions you are experiencing - scared and anxious - negative people around me, not sleeping, and so on. It was a tough run, getting all the tests done and through the surgery and recovery and going to rehab. I wouldn't wish it on anyone, unless they needed it. I still feel strain on my sternum if I carry something too heavy, and I can hear my mechanical valve ticking.
One of my coworkers was ALWAYS pestering me with questions about the surgery before I went in. I finally sent him an email link to a full open heart surgery video. He didn't talk to me after that, mission accomplished!
The book referenced before, "Coping with Heart Surgery and Avoiding Depression" was a great help to me and my parents, my dad in particular. I think he may have been more anxious about the surgery than I was.
I did wake up with the vent tube still in, but was so relieved and damn happy to be alive, I didn't even notice it. Then I went right back to sleep again.
I did get all my affairs in order - will, insurance, deeds and titles etc - just in case. And now they are done, what a relief my husband didn't need them!
Nausea and eating - right after surgery all I was allowed was ice chips. I demanded some ginger ale, and my nurse brought me some. I took a sip, and my tummy sent it right back up, almost instantaneously. That was the only time I ever felt queasy. My tastebuds took about 3 days to return, and I'm still not sure if that was related to the hospital food or not. Someone snuck some pizza in for me, and it was delicious, but breakfast the next morning was awful - maybe it was the powdered eggs? My appetite returned to normal in a few weeks, just about the time I could start running my house again. (I did ask for and receive help filling my freezer with easy meals!)
Yes, this is a tough thing to go through - physically, mentally, emotionally, socially. But it probably won't be as bad as you think it will, and it's TOTALLY worth it!
Keep your eye on the prize - hospital discharge and your own bed!
