relax, it's absolutely normal.
As a matter of fact, it is a good thing that you are "worried", if that worry does not make you anxious or something.
Because it means you are monitoring yourself and in a "learning" mode. That's very good. Keep it like that in the next years... and decades. Never stop learning and monitoring your weaknesses and your experience will make you a much better pilot than one who just doesn't care.
be happy!
