OK..I just had my brother take a look at the pics you posted and he said Libby needs to go to the vet. The shed it not the worse of her issues. He said by looking at the first picture she has a very SEVERE case of mouth rot. And seeing you are not a really experienced handler of amazons then he couldn't really walk you through how to clean it up a bit on your own so he said to get her to a herp (reptile) vet asap. Sorry for the bad news.
