She's scared, Mish. When people are scared they get understandably needy. In the hospital, you're a number. Maybe staff will come if I need something, maybe they won't. Patients often want those they can rely on, their loved ones nearby. That said, you carry on with your life because if you're exhausted and not getting your supports you are of no use to her anyway. It's hard when you see her need and part of you wants to be there 24/7 but you can't be. Is there a hospital chaplain who could also visit with your mom? Hang in there!
