Try following the Serenity prayer.
“God grant me the serenity to accept the things I cannot change,
the courage to change the things I can,
and the wisdom to know the difference.
Living one day at a time,
enjoying one moment at a time,
accepting hardships as the pathway to peace.
Taking, as He did, this sinful world as it is, not as I would have it to be.
Trusting that He will make all things right, I accept His Will.
So that I may be reasonably happy in this life and supremely happy with Him forever in the next.
Amen”
