Finally hit a bet I almost didn’t place

Had a bet today I nearly talked myself out of right before placing it.
My read hadn't changed, but I started worrying I was missing something late (nothing new had come up).
I put it in anyway and it won.

Has anyone had their confidence drop at the last minute even when the reasoning still looks the same?
I try to stay consistent with how I cap games.
Is there a point where you pass, even if you still trust your original read?
