It is only day two and I already cheated. Since I have a scheduled Ukraine call this morning, I decided to climb upstairs last night and sleep in my bedroom. I left a pillow and the queen size comforter, so I was able to sleep normally. The larger and firmer bed felt much better than sleeping on the small soft mattress. It is about 6:00 am and I will likely go back to sleep for a few hours before my call.

For better reference, this is the view from the second floor. I tried to minimize the items I brought downstairs. If I have to have the cast on for a long time, I will likely buy a firmer twin mattress, and start moving more stuff downstairs, including my computer and monitor.

Panic attack symptoms seem to change often. Right now, I do not have any cold or hot flashes, but I am having a lot more difficulty breathing.
