Untenable situation

Less than one minute read time.

Struggling to function on little sleep over the last week. I'm running on absolute empty. 4hours sleep a night average. Struggling to get dad to the bathroom and he's at serious risk of falling/tripping. My brother has had to return home and so I face tonight alone. Calls for overnight support currently unsuccessful. 

Dad's wish is to be at home. It's untenable for both of us. How the hell do I manage this?
