I don't know that I'll ever be able to accept uncertainty. I can accept it as far as life in general, I could be in a car accident, I could get cancer....but I can't accept it when it comes to feeling symptoms that even the boxes of antacids say should be checked out and ignoring them. For example, if I have symptoms that aren't potentially immediately life-threatening, I'm fine. When I thought I had stomach cancer I was able to go get tested, and the negative result was enough for me to get over it. I accepted that I didn't have stomach cancer then, and, if I do get it later, it will take a lot of time to develop, and I could deal with it then. With my heart, though, there's no time to wait and see. So now, every pain in my upper body makes me immediately fear that a heart attack is imminent, and even when I do get checked out, I know that the comfort is short lived because that doesn't mean that I couldn't have a real heart attack in the near future. So the next time I get a pain it starts all over again.
