Can you correct this paragraph for me, please?Four years ago, my sister who is younger than me was born. On that day,...

This is subjective, of course, but here is how I would
rewrite this:

Four years ago, my younger sister was born.
On that day, our lives changed. In fact, it is still hard to believe that she became
four years old just a short while ago. Before that, when my mother visited her doctor,
he said to her, "You should abort your baby because you have diabetes, and since you are
older than 45, it will be difficult for you and possibly put your life at risk." "I will
not do that," my mother said. "Everything that will come from God is good." To be
honest, I have been worrying about her, and there were a lot of nights I could not
sleep. I kept thinking, "What will happen to my mother when she goes to the hospital?"
The day the baby was due was the most difficult day I have faced in my life. I have not
forgotten those moments. We did not calm down until my father came and said to us, "Your
mother is OK now, and the baby is, too." That was the most wonderful news I have
heard of all.
