Life has completely fallen apart in a short time. How can I adjust without going crazy?

First of all, we need to understand that people consider the complete collapse of life to be evil. However, such a strict event is a blessing for a person, because the Almighty takes him out of an unviable form and encourages him to move towards a more viable one. And he does it with severity, not mercy. Therefore, we must rejoice.
Paradoxically, people seek only mercy and avoid severity. But a person should forget about the widespread and contagious desire for comfort and endless mercy. For if he is persecuted by mercy, his end will be near.
And by Thy mercy thou shalt destroy my enemies, and thou shalt destroy those who persecute my soul, for I am Thy servant.
David, Psalm 142
A person should think carefully about the verses of David, how exactly mercy destroys?
How to restructure? People are not capable. And a person needs to look and understand what he is being taught, to learn a lesson, to adjust his life scenario, to stand on a new path.
