How do you deal with PR reviews?

Lately I've been feeling down by my PRs and was wondering how you guys deal with what I call "PR Stress" basically when you publish a pull request, get a decent review, you work on amendments and by the time you push/go back to the PR screen there are more comments coming and the cycle repeats maybe once or a couple of times.

I'm starting to wonder if it's just me, and I should deal with it, learn to accept my mistakes and get better, or, maybe it's our PR workflow that should be more organized?

How is the PR review workflow at your workplace?

Thanks.
