The waiting part is the worst, I know there is nothing anyone can say or do to make you feel different until you get the results, but try and keep yourself occupied as best as you can and if you ever do feel the anxiety getting too much just drop a message on the these boards, there is always someone online who will chat!
Something that has helped some of my nodes over the years has been heat, I always use a hot bottle 10-15 mins few times a day on them.
