The Art and Curse of Worrying

I tend to be a worrier. And although I have worked on this rather negative aspect of my personality, I still worry. I over think, I fabricate, I am absolutely irrational and I evidently tighten up my whole body with this anxiety.
The Whiteman PTO again treated each of the staff to a neck and hand massage this year. When the young man was massaging my neck he said, "You definitely have the tightest trap of the day. Some others have been tight, but yours is really in a knot." After he attempted to relax me, I asked him what I could do. He showed me a few ways to try to rub the tenseness out of my own neck and shoulders. The he said, "And when you have stress---you just have to let it slide right off your shoulders." Good Advice and I have been repeating it to myself a lot these last few days. For we are going to Washington DC and I can imagine all sorts of bad things preventing a successful vacation.
I am driving out with Leslie's family, while my two sisters will fly to DC and meet us there. Washington is a place I have long wanted to see so of course, I believe it will never come to be.
The number one rule of a worrier is --- always expect the worst. The number two rule is ---what you do not think of will get you. So number three rule is --- think of everything that could possibly go wrong. Here is a partial list of my concerns.
We will have an accident.
Patty and Kathy's plane will crash.
We will get food poisoning.
Patty will choke on a peanut on the plane.
Someone will get sick with strep, appendicitis, the flu, a cold, etc---
We will have our luggage stolen.
We will make a wrong turn and drive into a river. (That is a nightmare of mine.)
Patty and Kathy will get on the wrong plane and fly to Alaska, never making it back to the east.
Some major catastrophe will occur in Washington. (That is also a nightmare I have.)
Some member of my family who is not going, will get sick, break a leg, or fall off a mountain.
My house will burn.
Annie the dog will drive Sherry and Marlin crazy.
I will get sick and make everyone else miserable.
I will never find enough bathrooms. (Another nightmare of mine.)
Anyone can see I have a problem I have reminded myself, as I rub my neck, to let the worries slide right on off my shoulder. Then I also often recite what that wise fish Dory said, "But if you never do anything---you never do anything."
With luck we are off to DC on the Fourth of July to have a perfect time. Unless-------
