Try changing the font, text size, and then printing out a copy (if possible). Just changing size and font is fine if you can't. It forces your brain to see the text like it's new, and you can pick up on any mistakes more easily that way.
I'm pretty sure you've had people before tell you your writing is fine, MaLe.
If you're that concerned, maybe ask your readers to comment on if it feels wrong or not?
I'm not really concerned, just curious what's bothering me. I swear it's not that bad, then I think it's trash and it goes back and forth. Right now was just a routine self doubt.
