Hi!! I wrote this in another posting but I think it applies here as well:
I don't know what religious group you belong to but as a traditional Roman Catholic, I say a set of prayers at night before bed and it seems to help tonnes, especially with feeling safe before resting at night.
Otherwise, some soft music like Pachelbel's Canon, or Bach's Air on a G String, or Handel's Largo from his Water Music Suite, or Mozart's Andante from his Eine Kleine Nachtmusik might help. Your choice, bro!
There are some prayers that I love and which appealed to me even before I became a Catholic. One is a prayer to our Guardian Angel. It goes like this:
Angel of God, my guardian dear,
To whom God's love commits me here.
Ever this day (or night) be at my side,
To light and guard, to rule and guide.
From stain of sin, oh, keep me free,
And at my death my helper be.
Another prayer I particularly love was written by St. Augustine. It goes like this:
Watch Thou, O Lord, with those who wake,
Or watch, or weep tonight,
And give Thine angels charge over those who sleep.
Tend Thy sick ones, O Lord Christ.
Rest Thy weary ones.
Bless Thy dying ones.
Soothe Thy suffering ones.
Pity Thy afflicted ones.
Shield Thy joyous ones.
And all for Thy love's sake. Amen.
Hope you'll sleep better soon!!
God bless,
Timothy
