Yes, it is very possible to live a normal life after surgery. I am back to normal, no doubt. But, I'm not foolish either, so I call it a 95% normal, which is pretty good I think, it would be a little crazy to expect 100% normal, wouldn't it? So, I'm on a low dose beta blocker now, but no big deal. So, I have some extra check-ups now for my pacemaker, but no big deal. So, every now and then I get a split second funny heartbeat feeling and my mind can't just ignore it, but no big deal. So, I know I will need another surgery some day too, but until that happens, no big deal either. Those are some of the things that are my 5%.
You do read more wrong than right, here, it's the nature of a help forum. A big percentage of folks disappear when they no longer need help because - guess what - they are back to normal. Many stick around too, though, even those without any big problems, thankfully. Tough recovery and worry go hand in hand and will certainly lessen over time. I wasn't close to normal at 1 month either, but you know what, how could anyone be, what with all the various issues usually in play: abnormal sleep, the constant struggle to restore physical capacity, frustration with mandatory restrictions, and most of all, the vivid memories of the worst moments of the surgical stay still fresh in our brains.
But a year and a half later, I hardly remember any of that, and generally never think about it. It didn't take that long either. I had a few "Aha!" moments along the way, when it hit me how much better I was doing. The first was at six weeks when I saw the surgeon for the first time since leaving the hospital. He told me everything looked good and that I should - guess what - resume doing everything normal again, no restrictions. It was amazing how much better I felt just hearing those words, even though absolutely nothing had changed physically.
I had another "Aha!" moment around 3 months or so, running around, full speed for the first time, in the back yard with my kids. Then, the final one, at 6 months, when I really did feel completely back to normal - perhaps a new normal, yes, but at least from my perspective, it feels just as good, if not better, than the old pre-surgery normal. For you, only time will tell. It may be a year, it may be two. Even after you get there, you will always probably be a little more sensitive to things than you were before. A weird heartbeat before you knew you needed surgery you would have instinctively ignored, but now, you may instinctively have those split-second (or longer) worries. Sure, it still happens to me too, but that I file again in my 5% category, and quickly forget about it.
Finally, I hope some of the athletes among us will chime in here, those out running marathons, etc. If that's not normal, I don't know what is. So, best wishes to you. I know it's not easy, and you've definitely had more than your fair share of issues so far, more than I had I know. It will get better, though, it will.
