Hallo Linda,
I am sorry to learn that you are having such a bad time.I've received your letter/message. It seems that you are a bit worried about your study and living in China. I do understand all of these happens to you. Particularly due to the language obstacles, you feel lonely and helpless.
I think all of these can be resolved as soon as you find new friends around you. You can learn Chinese quickly with help from your friends, and tell them about your problems. A good communication with them makes you like at home. Also you can ask your teacher for help if you have any problems. I'm sure you will settle down very soon.
Keep in touch and best regards,
yours,
Li Hua
