Dear agony aunt,
I'm writing to you because I have a problem and I don't want to talk about it with my parents or my friends because it's embarrassing. I think I'm being cyber-bullied by a classmate. Whenever I post a picture of me, he makes a nasty comment or dislikes the picture. One time he wrote "Stop posting pictures, nobody cares about you." That really hurt me! At school, he acts as if nothing happened - although that's not true, but as soon as he goes online, he starts to say really mean things and I don't know why or what I've done to him. I'm thinking about going offline forever. Can you please tell me what to do? I really need some advice.
Ben
