1.) I tell myself that no amount of worrying about it will make it not happen if it's in the cards, so I may as well enjoy life.
2.) I tell myself that I have done everything I can do to prevent this from happening so if I do get it, then I'll deal with it.
3.)I distract myself by thinking about almost anything else. (That works well for me as I'm easily distracted.)
4.) The moment I begin worrying, I immediately think of someone else who's going through a difficult time and then actively do something for that person. This can be a simple as sending a card. (That works the best for me.)
5.) I remind myself that all I am promised is today, and if I start worrying about tomorrow today, then I won't even have today.
I don't know if any of that helps, but even if it helps one person, it was worth writing.
