My mom gave me this and I wanted to share. Print this and use it to guide your thoughts. It's a wonderful prayer.
O Mary, Queen of Martyrs, look after my beloved wherever he may be. Talk with him during the silent watches of the night and spur him to bravery when he faces the cruel foe.
Keep him inspired by a never dying faith in his God.
Wherever his duty takes him, keep his spirit high and his purpose unwavering.
He is my choicest treasure. Take care of him, O Mother of God!
Keep him in health and sustain him under every possible circumstance.
Touch him with my smile of cheer and comfort and my full confidence in his every brave pursuit.
Fail him not and may he not fail his God, his country, nor the one who loves him.
