Got anger?

I just found out that Charlie will need to have surgery to remove a growth (bronchial cleft) from his neck. I am having a tough time processing this. I am full of rage and sadness that my child will have to suffer even one moment through this process. Through my confusion, I am praying for healing and comfort.

I just keep singing this song in my head

Breath of Heaven,
Hold me together,
Be forever near me,
Breath of Heaven.

Breath of Heaven,
Lighten my darkness,
Pour over me your holiness,
For you are holy.
Breath of Heaven.

(Mary's Song - Amy Grant)
