At hospital with Dee

I have been here with her all day. She has been given medication for her heart rate which is accelerated since yesterday. She has an upper respiratory infection. The Doctors feel because of her getting weaker that she may need to be put into a rehabilitation hospital for a period of time to try to get her strength back. Problem is her insurance will not pay for it. So back to square one with how does she get therapy when the insurance won't cover it? SMH
