Why sleepless?

 I'll rise at midnight... (Psalm 119:62)

Not to stew and fret that I'm not getting eight hours of sleep. No to thank and praise the LORD.

Go ahead and sing about it (used any common meter CM tune like Amazing Grace etc.):

Psalm 119

 61 The wicked wrapped me 'round with cords; your law I did not slight.

62 I'll rise at midnight, thanking you for all your judgments right.

63 I'm with those who your precepts keep and all those fearing you.
64 Your mercy fills the earth, O LORD; teach me your laws to do.
