Hi Doug,
Some ideas to think about:
1. First of all, I would have found a traveling Dad growing up to be rather exciting. It would have been neat for him to tell me about the places he went and why he was going. We could have looked the locations up on a map and studied about the history. He could call me or text me during his trip with information on neat things he thought I would like which would bring us closer together.
2. Try dealing with your anxiety issues more. Maybe your doctor could recommend something. I would also suggest meditation, mindfulness training, and journaling.
3. Would you be able to travel less or get a different position? Maybe the anxiety is partly due to burn-out.

I hope things get better for you and your family.
