There's a great old Jewish trick, which is so helpful in defusing situations from potentially over blowing into anger or other negative emotions.
It's the 'Mazel tov!' trick.
Here's a classic example of how it goes: Your setting the table to host special guest with a dish you worked all afternoon to prepare. Your child is in the kitchen doing their thing, when they inadvertently knock the dish to the floor. CRASH! In a split-second, hours of your hard work is splattered in the floor, and the china broken in a hundred pieces. Our parents have trained us to the Jewish knee-jerk response when you hear that CRASH: We shout' Mazel tov!' - just like under the Chuppah.
(Of-course you talk to your child about the importance of being cautious in the kitchen, just not when your blood is rushing. That makes all the difference in diffusing a potentially toxic situation.)
This can easily be applied to other situations, like the time you've been circling the city streets for thirty minutes until you found a parking spot, only to realize the store you came for had permanently shut its doors. Before letting a torrent of anger and frustration out, you quickly say the equivalent of 'Mazel tov!' or 'it was meant to be!'
Of course, this is more than a psychological trick. It's a reflection of a deep faith that Hashem is always taking us to a place ultimately best for us.
In the Jewish calendar we are now in the three-weeks of mourning, culminating in the fast day of Tisha B'av, over the collective misfortunes that have befallen our people throughout our long history. We don't merely mourn in sadness, rather we utilize the 'crash' to deepen our appreciation for the goodness that will ultimately be born as a result of our long journey. It's a time to reflect on the promise of our prophets of the messianic perfect world that we will soon experience, and study about and discover the beauty and significance of of our Holy Temple which once stood in Jerusalem, may it be rebuilt in our days. ( The 'Jerusalem uncovered' event next Friday is a great opportunity and timely).
As Jews, we have been trained that experiencing a CRASH is only the beginning of a new, deeper goodness... Mazal Tov!
