Hi Ed:
Welcome to OCF. You will find lots of support from the members here who have all been in your shoes before. Waiting to see a doc or for test results can be very frustrating. Try your best to stay calm and not to worry. Dont waste your time with that. I know its easier said than done, but Ive been right where you are now. My results were not what I wanted to hear, but I got thru it and now Im proud to say I beat it twice

Take a few minutes and write down all your concerns and questions to ask your doc tomorrow. If you can take someone with you thats always a good idea too. Sometimes we hear only so much before we kinda shut down and stop listening.
I wish you the best of luck tomorrow. Hope you are in the clear.
