Whacko, first, thank you for your service, Brother!

Second, use your military training to help you control your anxiety. Discipline your mind so that when you start to feel it, review everything that you know about the subject and examine what steps, if any, you have not taken that you reasonably could have taken.

Then, if there are any steps untaken that could improve your position, take them.

At this point, with nothing you could do, undone; direct your thoughts away from the issue stressing you. You know that you can only do what you can do, all else is in the hands of God/Fate and worry only causes you to miss what is good in life.

Life is good, brother. It is also uncertain, so focus on living in the now, not in the "what if" which is what anxiety amounts to.

Good luck, brother Whacko!
