You have a knack for getting along with higher-ups, and it's only going to get better over the next couple of years. Yes, years. That said, if you need to talk with an authority figure about a problem, even if it's an embarrassing one, now is definitely the time to do it. You may not be able to solve the situation even with their help or advice, but you definitely won't feel competent to do it without them. At any rate, it's worth a shot.
