Hi Dawn, So sorry to hear your news. I am not a religious person at all but there is a Prayer for Protection called "The Deer's Cry" (St. Patrick's Breastplate) from which you might find some solace. And I hope you don't mind if I post it here.
I arise today through the strength of heaven. Light of sun radiance of moon, splendor of fire, speed of lightening, swiftness of wind, depth of the sea, stability of earth, firmness of rock. I arise today through God's strength to pilot me. God's eye to look before me, God's wisdom to guide me, God's way to lie before me, God's shield to protect me from all who shall wish me ill afar and a-near, alone and in a multitude. Against every cruel merciless power that may oppose my body and soul. 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, Christ to shield me, Christ in the heart of everyone who thinks of me, Christ in the mouth of everyone who speaks of me, I arise today.
Best wishes all the way from misty Co Kerry, Ireland to you and your family at this difficult time,
Rita -
