Johnny,
I am a somewhat similar situation but more about the next round of tests since nothing beyond that scheduled. I am finding talking to someone else who has been through it has helped. I signed up for a donor buddy here as well.
And, I am focusing on getting as healthy as I can. I am continuing to eat healthier and going to do a little more running. Saw the suggestion for Yoga and I have done Yoga in the past. It can be relaxing as well as healthy.
Every person is different I know. For some folks running, for others the gym, or yoga, reading a book, or simply going out to a movie. If things proceed well then I am thinking of going with a group of folks on a quick out of town "guys night out" type deal to just forget some of the pressure on things and relax. As stated in my other thread, I found that the best advice someone gave me was probably the most obvious - the best thing you can do to help your recipeint is to to take care of yourself.
My suggestion is to take some deep breathes, call a friend, and just do something crazy/spontaneous to take your mind off from things for a while.
