You've got this 32. It may not feel like it at times, but you have shown improvement. When I was in the hospital I did supine exercises, sat at the edge of the bed a lot concentrating on my posture along with my breathing techniques, and even did some seated exercises while at at the edge of the bed. If you need some exercises, I would be glad to email the ones that I give out to my patients all the time. The biggest thing right now is to be active in some way. If you want to walk, ask for help getting to the restroom or just practice getting up from the bed to the chair (only perform if you feel safe enough to do it yourself). That would be a good place to start for function and walking.
In regards to nights, it was tough to sleep most nights to the point that the doctor prescribed Ambien for me (which I never took). The first couple of nights they gave me Benadryl and Tylenol, which didn't help a whole lot. I finally just said to forget it and didn't take anything. I slept better but it was because I started feeling better.
Also, put a pillow between your knees/thighs when you are on your side. Your pelvis/hip are probably pissed off at the alignment of everything. Make sure to alternate sides at least every couple of hours at the most during the day.
Again, keep your head up. You will get there. Continued prayers for you and your family.
