Don't worry but work through

It is natural to get worried when things don’t go the way we want; effective way to come out of the worry zone is to work through the problem than just over think, whine and regret about it. Simple way to start would be to write down the problem statement and possible reasons and resolutions we can think of. Now based on our day-to-day learning we should refine the reasons and resolutions which we wrote last, this way eventually we can have the best possible solution, deeper and better understanding of the given problem, and the ability to overcome it.
