用英文写一篇对朋友(同学)的感谢信,可从对你的帮助、学习等来说,不少于5060词.注意,是英文版!

Dear×××,
I am writing to show my sincere appreciation for your generous help
Thank you for helping me and give me so much care.Whenever I have trouble in learning , you are always patient to help me.
When I lose confidence, you always encourage me‘everything is going well’.all this you not know ,but really thank you very much!写得不好,不喜欢不要骂
再问： 不错，语法、感情都挺好的
