Your mom is really a superwoman I would say. Same goes for my father. My grandfather died when he was in grade 6th and since then he has taken care of his family by giving tuitions to other kids. He used to study under the street lights because he didn't have electricity that time and managing everything on his own was a real challenge. But he grew from that situation and has given a great life to his family. I feel really lucky to have a father like him.
