I am a 17 year old girl in high school, and my grandmother is dying of cancer. She had helped raise me and my older sister because our mother was a single parent, and now she has little memory of me. My mother and sister tell me I am selfish because I do not want to care for her, but it's just that I never had a death in the family and don't know how to go about this. I just need some opinions... I don't think that I should be caring for my grandmother alone, when she can't even walk. What if she dies in my care? Should a 17 year old really have this responsibility? Am I being selfish? Please, I don't want to feel alone on this.
