Very true. I remember saying the Serenity Prayer about every five minutes after my husband died just to get me through the day.
The last line — “And the wisdom to know the difference.”
Recently my wife was in the Hospital with a recurrence of a bacterial infection that caused her to have an altered mental status. The Doctors kept trying to tell me that it was a late onset mental disorder. I prayed that prayer it seemed like every 5 minutes until they came around to my way of thinking. I kept being persistent but polite and reiterating the facts of the case.
That prayer got me to sleep at night along with the Divine mercy chaplet.
