Psalm 91
1-He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.
2-I will say of the LORD, He is my refuge and my fortress: my God; in him will I trust.
3-Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence.
4-He shall cover thee with his feathers, and under his wings shalt thou trust: his truth shall be thy shield and buckler.
5-Thou shalt not be afraid for the terror by night; nor for the arrow that flieth by day;
6-Nor for the pestilence that walketh in darkness; nor for the destruction that wasteth at noonday.
7-A thousand shall fall at thy side, and ten thousand at thy right hand; but it shall not come nigh thee.
8-Only with thine eyes shalt thou behold and see the reward of the wicked.
9-Because thou hast made the LORD, which is my refuge, even the most High, thy habitation;
10-There shall no evil befall thee, neither shall any plague come nigh thy dwelling.
11-For he shall give his angels charge over thee, to keep thee in all thy ways.
12-They shall bear thee up in their hands, lest thou dash thy foot against a stone.
13-Thou shalt tread upon the lion and adder: the young lion and the dragon shalt thou trample under feet.
14-Because he hath set his love upon me, therefore will I deliver him: I will set him on high, because he hath known my name.
15-He shall call upon me, and I will answer him: I will be with him in trouble; I will deliver him, and honour him.
16-With long life will I satisfy him, and shew him my salvation.
I know a Vietnam soldier that prayed Psalm 91 when all around him was nothing but devastation. The only thing that kept him going was praying this psalm. It gave him the strength to keep trusting in God for his protection. He came back home to his family well and safe and a more committed Christian than before, for he knows that it was God who kept his angels around him all the time he was there. So when you feel like you can't pray, remember to go to this psalm, plus many others that can be lifted to our Heavenly Father as your prayer, here is another good example Psalm 121. I will continue to pray for your family and your physical healing.

John 14:27
Peace I leave with you; my peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.
