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 are 39 . You said that nobody would care if you left home. What about your 40 ? And other family members? It seems that you are very 41 . You’d better go to a doctor or talk 42 your parents. They will be able to help you. Second, I’m sure there’s someone else in your class who feels lonely, 43 . You never know 44 other people feel. Try to make friends with your classmates. And you could 45 a club to meet new people and make friends, too. You 46 find happiness in yourself. So my 47 advice is to write a list of all the good things about yourself, learn to like yourself, and then 48 will see your confidence (信心)and like you, too. Editor
