Here are two very nice prayers that a member of WPC just sent me that I would like to share. She says they have been helpful to use when she can't sleep.
This was written by Teresa of Avila.
Let nothing disturb you.
Let nothing frighten you.
All things pass.
God does not change.
Patience achieves everything.
Whoever has God lacks nothing.
God alone suffices.
This is part of the "breastplate prayer" of St.
Christ with me, Christ before me, Christ behind me,
Christ in me, Christ beneath me, Christ above me,
Christ on my right, Christ on my left,
Christ when I lie down, Christ when I sit down, Christ
when I arise.
