Gracie is right learning through Skype can be very helpful. You said you didn't have any non-Chinese friends to practice your English with at school. You might try volunteering at a hospital passing out the flowers or magazines to people in the hospital or volunteer at an animal shelter or something else you might enjoy. You can make friends through volunteering and have opportunities to practice your English more.
