Can you please help me with some words?

Hello! So, I need help with some words.
I’m writing at the moment and need some verbs.
This is sort of a request in two parts…
Part A: I need a verb that best describes that reaction of “noooooo” but in a shocked and appreciative way, you know that noise you make when you can’t believe something, but love it at the same time? I need a word for that
Part B: I want all of your amazing and interesting words to expand my vocab and make my writing better! I know you jellies have some amazing words to share and I’d love to hear every one of them!
Thank you so much!
