I know how hard it is....the waiting. Do you get to stay in contact fairly regularly? I know that helped me a lot, but it was hard on the rest of my family since I pretty much refused to be away from the house just in case our son was able to get online or make one of those rare, but precious and short phone calls.
I am very lucky....Jon is able to email me at least once a day unless he is on a mission...most emails consist of *I’m okay, just checking in*.....that’s all I want or need....
