SadHub, sorry to hear your morning is rough. I wake early, too, and have trouble getting back to sleep. Not so much anxiety as 'why?' - why is H doing this/acting mean & cold, etc.
I felt calmer after we separated and I moved. I wonder if the limbo and feeling powerless is what is causing you anxiety. I saw in your signature it said waiting for W to file for D. That's hard, is there any way you can reframe your situation to feel more empowered?
Also, I think you can let D17 see that you are down... as long as you also let her know it's going to eventually be okay.
