My dear son,
I think my life (be) long enough. And I won't be able to visit you any more, but would it be too much to ask you could come and visit me once in a while? I miss you so much! I am so glad when I hear you are coming to the school fora meeting. But I have decided not to go to the school I am seriously ill.
I'm sorry that I only have one eye, and I have been an embarrassment（尴尬）for you. But before I leave this world, I have to tell you one thing that I have kept in my heart over twenty years. When you were very little, you got into accident and lost your eye. As a mother, I couldn't stand (watch) you grow up with only one eye. So I gave you (I). I was so proud you could see the whole world. I was never angry with you for anything you (do). Sometimes when you were upset with me, I thought to myself, "It's because you (love) me." I miss the time when you were still young around me. I miss you so much. I love you. You (be) the world to me. Wish you a safe trip.
Your mum
