1 - 18 "Save me, O God, for the waters have come up to my neck." The psalmist is suffering and it reminded me of this Radiohead video (especially from about 2:03 on).
18 - 28 - The psalmist asks for protection from God's enemies.
29 "I am in pain and distress; may your salvation, O God, protect me."
30 - 36 - Praises
This is an excellent psalm for times of great stress.
