I am sorry to hear that you are usually ill.I think keep health is very important.you can do these things as more as possible every day.
You should eat breakfast on time .Then you could do morning exercises.Like running,piaying basketball,talking a walk...Playing sports is good for your health.
And also you should eat vegetables and fruit.Try to eat less junk food.Why don't you drink milk?You have to have enough time to sleep,or you will fell tired the next morning .That'all.
I hope you fell comfortable soon.Looking forward to your reply.

聽說妳經常生病，我很難過。我認為保持健康非常重要。妳可以每天盡可能多地做這些事情。
妳應該按時吃早餐，然後妳可以做早操，比如跑步、打籃球、散步...運動對妳的健康有好處。
妳還應該吃蔬菜和水果，盡量少吃垃圾食品，妳為什麽不喝牛奶？妳必須有足夠的時間睡覺，否則第二天早上妳會感到疲倦，僅此而已。
我希望妳很快就舒服了。期待妳的回復。
