lake Please can you tell me the name of this movie that is about a late 1800's or early 1900's "hospital"?

In my memory it featured Robert Downey J.r and Rosie Odonnel but I think I am mixing it up with Exit to Eden. This movie has the main guy sleeping with a woman who is deathly ill from anemia, it's a dark comedy about a pysichiatirc hospital of sorts. I watched it in the 80's or 90's.there
