Dear Pet,
   Without knowing more about you, it's hard for me to give you some good advice.
   But first, I am sure that you are1 . You said that nobody would care if you left home. What about your2?  And other family members? It seems that you are very3 . You'd better go to a doctor or talk 4 your parents. They will be able to help you.
Second, I'm sure there’s someone else in your class who feels lonely, 5. You never know6other people feel. Try to make friends with your classmates. And you could7a club to meet new people and make friends, too.
   You8find happiness in yourself. So my9advice is to write a list of all the good things about yourself, learn to like yourself, and then10 will see your confidence (信心)and like you, too.

    吴广素爱人，士卒多为用者。将尉醉，广故数言欲亡，忿恚尉，令辱之，以激怒其众。尉果笞广。尉剑挺，广起，夺而杀尉。陈胜佐之，并杀两尉。召令徒属曰：“公等遇雨，皆已失期，失期当斩。籍第令毋斩，而戍死者固十六七。且壮士不死即已，死即举大名耳，王侯将相宁有种乎！”徒属皆曰：“敬受命。”乃诈称公子扶苏、项燕，从民欲也。袒右，称大楚。为坛而盟，祭以尉首。陈胜自立为将军，吴广为都尉。攻大泽乡，收而攻蕲。蕲下，乃令符离人葛婴将兵徇蕲以东。攻铚、酂、苦、柘、谯皆下之。行收兵。比至陈，车六七百乘，骑千余，卒数万人。攻陈，陈守令皆不在，独守丞与战谯门中。弗胜，守丞死，乃入据陈。数日，号令召三老、豪杰与皆来会计事。三老、豪杰皆曰：“将军身被坚执锐，伐无道，诛暴秦，复立楚国之社稷，功宜为王。”陈胜乃立为王，号为张楚。当此时，诸郡县苦秦吏者，皆刑其长吏，杀之以应陈涉。
