Dear limei：
I am so sorr about that.I think you don't need to do as same as your parents told you.Eventhough it's good for you to learn language and jion some after-school club,it's bad for your body and heart.I think you should choose the acyivities you like.If your parents don't agree,you can tell them your reasons.At the same time ,you must have enough time to sleep,it's very important for a student to sleep well.Hope my advice will help you and you can get out of the pressure.
John
