Go ahead and ask.
Whether it's asking for help or asking that burning question, don't let unanswered questions linger. After all, having an answer (no matter what it is) is better than the anxiety of being left in the dark. Be careful, though. If you're asking for something in particular, you might just get it!
"He who asks a question is a fool for five minutes;
he who does not ask a question remains a fool forever."
-Chinese proverb
