I am Very Grateful to My Mom

Now, I’ll graduate from middle school. I am very grateful to my mom because she has done much for me. I think words can’t show my thanks to her. 
My mom is an excellent teacher and we are in the same school. She works hard and often goes back home very late. I remembered that once I was very worried about a quite hard problem from my homework. She helped me in time though she was too tired at night, and I was so thankful at that time. So my eyes were filled with tears.
I would never forget it. From my mom, I got not only help but also the deep love. Thank you, my dear mom.
