Dear Wang Lin,
I am sorry to hear that you have been sick for three days. Are you feeling better? I know you're always working hard in daily life, since you never go to bed before the midnight every day. But it is not a good habit to stay up late at night. It can harm your health and your energy that you may feel exhausted and low-spirited on next day. Don’t worry about the classes. I will lend you my notes after you come back to school. Now what you need is just a good rest and a balanced diet. Perhaps we should have sports together regularly after you come back to make us stronger. Take good care of yourself and I hope you will recover soon!
Best Wishes,
Li Hua
