The question isn’t “Am I good enough?” It’s “Am I getting better?”

Good enough has no fixed standard, so it can be asked forever and never answered; whatever you achieve, the bar moves up with you. Getting better is answerable: it has evidence attached, and it turns a bad day into information instead of a verdict. Same effort, different weather inside it, purely because of which question is running.

Pick one thing you can measure and write down where it is today. The number of pages, the time, the reps, how often you spoke in class. Check it in a month. You are not trying to prove you are enough, which is not a provable claim; you are looking for a direction.
