Lucy,
I received the letter you written to me.You said you had big pressure , because of your study.I am writting to you to give you some advice.
First of all, you should try your best to smile.Smile will give you a good attitude.What's more, you can do something you like to relax yourself, for example, lestioning to the light music, watching the films.All in all, you should creat happiness for yourself.
I wish these ideas can help you. May you be happy.
Yours,
Lily
