One of the approaches that I personally find useful is to cultivate the thought: If the situation or problem is such that it can be remedied, then there is no need to worry about it. In other words, if there is a solution or a way out of the difficulty, you do not need to be overwhelmed by it. The appropriate action is to seek its solution.
