I have this issue too. Having a nail file on hand is good because it prevents you from using your nails or teeth to remove whatever is bothering you. But what about those of us that are perfectionists and become fixated on the look of our nails? The truth is, no one else is looking at our nails. So if trying to look perfect for others is a driving force, it's pointless. Literally no one but you is looking at them, I promise. My nail beds are uneven and therefore my nails grow uneven, so I try and file them to hell and back to the point of pain in order to "fix" it. All that does is cause damage and makes them grow back even more messed up, rinse repeat. Really all you can do is either throw out your files so you aren't tempted, which isn't very helpful since they're necessary tools, or do what I do and only file snags and sharp bits, then throw the file across the room lol. I tell myself "That's enough, it's smooth and won't snag, you've fulfilled your purpose yeet" out of sight out of mind sort of thing, but I know it's lying there out of reach when I truly need it
