Ah, so many people here who have experienced the same.
It has happened to me, 6-9th grade was one of the worst periods in my life. I didn't get along with kids in my class, I had only one friend. When I tried to speak to other kids they always pushed me off, as if I had done something wrong, and there were some terrible people who made very nasty comments about me. At one moment I remember myself reading aloud at home not to lose my voice, because I talked so little. Now nobody's bullying me but I can't say that I would have very close relationship with my class-mates, all my best friends are not from my class. I don't know which is the cause and which is the consequence, but I really don't like spending much time with people and often movie or book characters are closer to me than the real people. It's strange that I can feel completely satisfied and even happy reading/watching films/doing anything I like when I'm alone, but meeting people often brings me down.Maybe it is wrong, but I don't think I can change this. I also would like to be a psychologist, but I know it is very hard and I'm not sure I could really help those people.
