I was struggling to fall asleep for five or six nights. I knew it was due to anxiety which was caused by fear. I happened to open up a book I had on faith and found several passages I had underlined. The words were just what I needed to allay my anxiety. I kept referring to them the next few days. I started sleeping better. And not taking so long to fall asleep. It was a book I had not opened in a long time. I must have been dealing with similar issues before. It was just the right words I needed to hear. Books can be lifesavers.
