Okay. Here's what I'd do.
Take the story down. If you're revising it thoroughly, that's a defunct draft which has no value - few are going to want to read that then read the "proper" version. If you're not revising thoroughly, revise thoroughly anyway and see previous comment.
The feedback you've received is immaterial from a Qing POV. Unless John Updike has been to your Wattpad and declared you marvellous, it's not going to matter. It's like saying your mum really loved it. The time when this would be wrong is if you were a massive success, like hundreds of thousands of marvellousness success. The kind of "mention this story and anybody who uses Wattpad knows it" success.
If you want to keep it for yourself, I'd imagine you might be able to set the MS to "private" so nobody can read it, but the comments remain. That's a guess, I've never used Wattpad.
ETA Or, as Solunar says, leave it as is and write something new.
