请用英语写篇对老师的感谢信

Mrs***:
I am so thankful to write the letter to you to express my admiration to you!You have helped me a lot in studying.I will never forget the help you give me.Now I am captable of learning well.But when I am your student first,I was so awkward.Although I am eager to learn well and to be a super student,I worked hard improving few!
You are so temperate and guide me with great patient.Although you are very stricked to us,you never criticized us whenever we made mistakes.I am so moved by you.The best way is to study hard using the method you teach me.I acknownledge that learning anything is not a kind of mechanical work. There must be something associated with another.Method is no less important.Now I am so delighted and pleased with the mark granted!
It is self-evident that you helped me a lot.Whenever I meet any Waterloo,your encouraging is always remind me of the word you told me.Now I knew nothing can frustrate me any more that is because of you. Thanks
