"O Lord, you brought up my soul from Sheol, restored me to life from among those gone down to the pit."
We can pray this psalm of gratitude for the healing that God has provided us.
And not just healing from physical diseases. Sheol is that lowest of places, a separation from all friends, a separation even from God. We are in Sheol at those moments of greatest distress and isolation.
But, even in Sheol, we remember our Lord.
Here's Robert Alter's translation of verses 11-13 (A Translation with Commentary, The Book of Psalms):
Hear, Lord, and grant me grace.
Lord, become helper to me.
You have turned my dirge to a dance for me,
undone my sackcloth and bound me with joy.
O, let my heart hymn You and be not still,
Lord, my God, for all time I acclaim You.
