My father got a stroke a few days ago, because of exhaustion and the reason was that he could not take good care of himself. He's in a difficult situation, he can't even move, we'll have to take care of him - whereas his father is in a much better shape but he refuses to do simple things like going to the bathroom to urinate. He's a difficult person.
We're facing financial issues currently as well. I'm looking for a higher salary job + studying, same with my siblings (one if them is a minor). My mother will have to take care of my father who can't even move. But my aunt now assumes that now we'll have to take care of her father. She tries to give this responsibility to us, which I and my siblings are not willing to take. We have to work to bring money to home, we won't be at home and sitting with an older person daily. It seriously affected our father, who was not able to handle so much.
How can we talk to our aunt? We're nervous because we don't want to cause conflict. We still want to maintain a good relationship with her, she's also a medical worker. But we want to make it clear that we won't be able to pay/become caregivers for our grandfather and she has to take responsibility for her father (She has not even seen him for 5-6 years, I don't know what's wrong with her). We need your help.
