I did finally find a solution. After our trip out, I went to the games room. This is the room near her basement cave (aka the bathroom and laundry room). I "slept" in the recliner for about 3 hours. She didn't bark or pace during that time.
At about 5:30, I really needed to go back to our bed as my back was sore. She started the barking and pacing until the Man got up around 6:30. Then she was better.
I have Wednesdays off (I am working compressed hours which means it is harder to visit you all on Monday, Tuesday, Thursday and Friday, but I get 3 days off a week), so I was trying to get some of the sleep I lost. As soon as the Man left, the panic started again.
It seemed that today, she could only be calmer if one of us was up with her. As I write this Wednesday morning to prepare for tomorrow, she is asleep in the chair beside me. Phod is off sleeping too because she kept him up.
I don't know what we are going to do with her. We need to be able to have the windows open in the summer. Phod goes to the vet in a few weeks for his check up. I will speak to our vet about it then.
This video was taken Wednesday morning. She is fairly calm in it, but you can see she is demanding comfort, that clearly doesn't help.
