It seems to me that you did the very best you could against, what is often, a wicked, heartless and pernicious system infested by 'professionals'. There may well be some professionals who are competent and caring (I didn't meet any when trying to care for my Dad) but mainly they seem to be ruthless, heartless, arrogant gits, with absolutely no knowledge of their chosen 'calling', who go out of their way to avoid their responsibilities. 'Professionalism' is the one of the curses of modern society.
