Hang in there. You'll fall into a rhythm with the kids and you'll get used to it (sad, though it is). Be sure to ask for some help. Ship the kids off to Grandma's or a friends or something to give yourself a break here and there, OK? You need to take care of yourself, too. I remember the days when hubby was gone sun aft to friday late evening. It was not fun. I can sympathize with your heartache. Hang in there. Be strong for your kids.
