The narrator blamed the angels for the death of her. He said that they were happier then the angels in heaven, so it made them jealous.
Here's some tips about formal language:
1. Usually, it's best to replace abbreviations with their original word. For example, if you wanted to say "it's", you'd say "it is".
2. Use vocabulary words that are more descriptive. This doesn't nessesarily mean more complicated words. For example, if you were to say "Jellyfish can live without causing harm to people", instead of "live", you could say "thrive".
3. This is just a Grammar mistake - "jellyfishes" isn't a word, but "jellyfish" is (just like "fishes" isn't a word).
Hope this helps!
