求一篇英语作文!要求：假如你是Alice你的朋友Jimmy给你发来邮件,说他在考试前常常感到紧张,睡不好觉,问你该怎么办

Dear Jimmy,
Sorry to hear that.In fact,exam is just a way of testing ourselves and no need to get nervous indeed.When you lie on the bed,just take a deep breath to relax yourself.At the same time,you tell yourself exam is not so important.If all of these cannot work,try counting sheeps one by one.That is my recipe of solving sleeping problems,please have a try!
Yours,
Alice
