I know its hard to understand but I was going to school where everyone knew each other. We all were spending time together. There was group of people who were making fun of everyone else. They wanted to be cool. As I said Ive had a reputation the most polite, quiet, not talkative guy. For example i remember how we all were sitting (my class and other) in locker room. One guy was laughing at few people but especially at me, always focused on me and told "can you talk ;), look at him he usually doesnt say anything haha, hes funny" everybody was laughing hard at me, I wanted to leave and cry... (why I was so polite kid and tried to laugh with them but inside it hurt me so much) or there was also very shy, unattractive, strange girl. He was asking among all "how's your girlfriend?" "What are you talking about with her" "Of course it was funny for everybody... I felt so isolated. Then nobody respected me. I feel so weak and I feel like if they wanted to they could destroy me mentally so easily.

I go to other school where I didnt know anybody before. Here is fine but Im afraid of going out/coming to party with them. I dont wanna let them know that there are few people who like to humiliate me in front of public. Im introverted but it makes me more and more isolated from people. I have never had a girlfriend. I feel like in these situations in locker room where they were making fun of me. Nobody was as humiliated as me. He was making fun of me among whole school. Some people laugh at everything I do for no reason like this guy or start to say that I am freak who doesn't talk at all whenever they see me because of few people... I dont think its ever gonna stop ;( Thats why Ive thought about suicide, thats why Im afraid of people/facebook. I remember how everyone was talking and laughing at me. It destroyed my life. I just go out only to shop. I trust only people from my family. Maybe I should tell my parents about it? Id like to make friends/talk to people but because of my expierences in the past I prefer to not talk at all and hide from people. My whole life he same people laugh at me since schoolhood :(
1.If somebody told me that he heard something embarassing about me or that I dont talk at all how should I answer? for example "what the hell are you talking about, you its funny?"
2.If that guy who always laughs at me will start again to make fun of me in group, how should I answer? Pls help
