I see what you mean.Yes, Hospitals are very bad places to visit. I can't stand being in one. And, sometimes they can let you go, but they don't because it runs the bill higher. You have to tell the doctor you want as soon as possible, and you don't care.
But, an example is, they knew my daddy needed stints, and they knew my mom needed stints, but they kept it a secret until it was too late. Then they came out and say they needed the stints, but it was to risky to do it. And, they let my daddy suffer almost he's entire life with pain, when the stints could have made it better for him.
I'm so sorry for your parents and for you having to endure seeing your parents suffer.
