Bloody diarrhea 50+ times a day is not normal! I had Crohn's with diarrhea and went about
20 times a day and thought that was a lot. You poor thing, this is no way to live!
And, for doctors to say there's nothing wrong with you is just crazy! You need to find a gastroenterologist who will do every test possible to find out what's going on.
I know for a fact that a temporary ilestomy would give you relief, because you would not have to live in the bathroom anymore. You would be able to eat every day and have a life.
