1、Dear Tim，

  I’m sorry to hear you are unhappy．It’s difficult to get used to the life in a foreign country very quickly．I have some suggestions．Maybe they will help you get out of the trouble．First of all．try your best to listen to what others say but you don’t need to understand every word．Then don’t be afraid of being laughed at．If I were you．I would talk with my teachers and classmates more often．Also eat more fruit and vegetables．And take a walk before going to bed if you can’t sleep at night．

    Everything will get better soon．
