Washbe, I am so sorry this isn't getting any better.
Please make certain that the doctor and hospital know that staying with you is not an option. I used to get so upset when medical people would just presume I would let my son move back in and take care of him. I had to make it very very clear that moving to my home was not an option.
Perhaps they will find homecare and if not they should keep him in the hospital. However this unfolds is out of your hands, dear Washbe, it's time you got some rest for yourself.
Keeping your boy and you both in my prayers.
Hugs
