Hospital kicks me out with 4 hours notice when I can't use my leg until Labor Day

My leg is broken in 5 places. I had surgery, a rod, plates and screws. I agreed to go to a rehab facility after. BUT THEY ONLY GAVE ME 4 HOURS NOTICE to leave and are making me arrange my own transport. With a leg that I can't use until Labor Day.

F$%K them! Why didn't they tell me this yesterday??!!!??? Why?
