Cats are pretty easy :) I have my two dogs that I love to bits, they can't do the cat's job though (they do a different things for me and I wouldn't be without them either!).
Well that's a pain about the doctors all saying different things :< I don't have any helpful experience or anything to share unfortunately, I was repeating what someone else had suggested to me once. I'd ask if you've gotten second or subsequent opinions but sounds like you have had a lot of opinions already! Well even if you don't feel okay now and like it will never be okay again, you will be okay eventually, hopefully sooner rather than later :) Hope you can find whatever help you need to get to that okay point :)
