Prayers for Healing .. please help!?

My grandma has been in the hospital for almost 2 weeks now and will continue to be there for at least another 2 weeks for sure. She has a degenerative disease with her bones.. I'm not sure the name of it (too technical) haha.. also, she has a UTI (urinary tract infection). She is unable to walk right now and is very sore and in very much pain. She feels discouraged and depressed. She does not believe she'll ever get well again or come home. Although the doctors confirmed that she will return home, she has a very negative mind-set right now and is worried for herself as well as my grandpa. Understandable! I would like to bring her an uplifting prayer to boost her spirits. A prayer for the healing of the sick. We are Catholic.. Roman Catholic to be specific. Any prayers will do =) Thank you for your help! I appreciate it.
