How Do I Stop Worrying All the Time?

What is the purpose of life?

This question has no answer.
This is because life already existed before the thought of why it exists
emerges in one’s consciousness. It is impossible to find a reason for our
being because our thoughts are a byproduct of our lives.

Life has already been gifted to you and will naturally end when you die.
In the life you are already living, the choice you can make is whether you will live happily or miserably.
