I can certainly understand your worries, and the worries of your kids. I would be panicked too, with the amount of back and forth that's gone on. I wish I could give you safe, real hugs. We understand within the context of our own situation with our T, but it's not near to the level that yours has been with your T leaving the country so much. I would acknowledge to her that you know she has a lot going on, but that you're worried, and need time with her, especially if she's leaving, as much warning would be nice, and if she can see you, even if it's just a quick "Hi", hugs, "I'll be back", grab a drink, type thing!
