Dear Tom,
I’m sorry to know that you’ve got flu. Are you feeling any better now? I’m really worried about you.
In order to help you get well soon, I strongly advise you to get up early in the morning and never stay up too late. I believe a healthy lifestyle will make a big difference. Besides, you should be on a healthy diet. Don’t eat too much fat or sugar. You can try some fresh fruit or vegetables, which will be of great benefit to you. What’s more, if possible, take regular exercise or take part in outdoor activities with friends, which will surely keep you fit.
I hope you will be back with us soon.
Yours sincerely,
Li Hua
