帮我用英语给爸妈写一封信

dear father and mother,
are you confused that you get a letter from me?
Yes, it seems to be the hardest for parents getting a letter from their child. but I want to tell you that I'm no longer a little boy/girl. I can understand more your feelings. I know you want me to be better and better. And I am still working for it. Sometimes I can't control myself and turned to quarrel with you. I know it's my fault. And I want you to forgive me. at last, I want to say thanks to you again for taking care of my life and encouraging me on my study. I promise to work harder on my study, not only for you,but also for my better future!
love you
yours,
xxxxx
