1. Your mistake was stopping. Even if you are taking a break from publishing, you need to keep writing. I don't care if it's 500 words a day, you write SOMETHING. I'm taking a break but I'm still writing something. If you want to get gud, the solution is to write three times what you need, throw out half, and then slowly pare down to the bare minimum. Writing is, was, and shall ever be a numbers game. Half of what you write will be below average, by sheer mathematical certainty. So use that to your advantage.
Write three times what you need, knowing it doesn't HAVE to be good. Relax. Let go of the need to have every word be the best.
2. Get help - If you get in the habit of writing more then you need, then getting rid of the shit and paring it down to the absolute bare minimum, then you should next look to getting an editor. Find someone, ANYONE who has a halfway decent writing style, and ask them to help with the story. You get it into a rough draft situation, then ask the other person to review it and make any changes they think would help. They send it back and you get to rewrite what they send you.
Even if you hate everything they do, that's okay, it'll force you to rewrite what you did and I promise you, your rewrite will ALWAYS be better then the first draft. If you can't find anyone, do what I do, feed your story into ChatGPT one paragraph at a time and ask for a rephrasing. Use V3. Why? Because v3 is TERRIBLE. That's the POINT. The whacky way it rewrites things is great for making you look at your story sideways.

If you are really screwed and need a second pair of eyes, let me know. 'm taking a break from publishing myself while I sort out a dozen or so RL issues.
