my sister

hello my sister was diagnosed last year and has been taking a long time to recover. I realize that this will take a long time but I don’t really know how to encourage her to do anything she is in so much pain still and is at a sub-acute facility. She has a trach,foley, and feeding tube and she recently cannot stop throwing up. She states that she feels the same as when she first got sick. Can someone please inform me on what I should do I feel hopeless
