Dear Jin Jing，
Your problem is common one among middle school students．Maybe the following
advices can help you．First in all, believe in yourself．Your greatest problem is that you lack self-confidence．The first thing you must do it is to smile at your classmates．One smile speaks loud about your wish to make friends than any word．Your smile will show that you are friendly to him．Next, trying talking with a student who is as shy as you or who share the same interest as you．You can discuss your studies with a classmate and you can also talk about your hobbies．Unless anyone is in trouble, you should be ready to help him or her．Once you have confidence, you can make as many friends as possibly．
Yours,
Lily
