Deuteronomy 28:65-67

And even among these nations there will be no peace for you, and no rest for your feet: but the Lord will give you there a shaking heart and wasting eyes and weariness of soul: Your very life will be hanging in doubt before you, and day and night will be dark with fears, and nothing in life will be certain: In the morning you will say, If only it was evening! And at evening you will say, If only morning would come! Because of the fear in your hearts and the things which your eyes will see.
