I think you are doing amazing with your circumstances. I wish I had something helpful to say about your trip, but I don't, so I guess I will be quiet (smile).
The one thing that seems really difficult to me is that you are away for 5 days a week. I have not read your whole thread so excuse me if you have answered this, but was your working away like this before the Bomb?
And before the Bomb date, when you were away, how often would you communicate, and what sort of communications did you have with your W? How is it now?
