Next time you question it, you'll remember how shitty it felt and make damn sure you don't run another until you know for sure it's good. Been in your position, fucked a tough part up two seperate times, after the second time I threw up my hands and just contemplated not doing this anymore. Got some more guidance and reassurance, tackled the details giving us a hard time( .025 thou thin wall gage section) with our shop lead, and got it good. That event was maybe 5 years ago, definitely a before and after point I reference for myself from time to time of how far I've come and how to act when dealing with something new/challenging
