I can relate to you entirely "NoNameGirl". School is painful.
I am 15 and dropped out of high school when I just turned 14, and went to a 1 term course for those who had mental/intellectual disabilities, because school was just too hard to cope with.
In my lunch breaks, I would walk around and around the high-school grounds aimlessly until my next class started. I couldn't stand people knowing that I was alone, so I walked aroung looking like I was looking for someone. Also I couldn't go up to people and join in their conversations, because I was clueless of how to maintain them.
I never had one friend in all of my school years, from when I was 5 years old, until I left. Those who I thought were my friends, were using me to do things that were socially un-acceptable. Such as telling someone that they were fat, or asking a teacher if they were a virgin (this did really happen). I was 6 years old at the time. I was completely oblivious to what was "the norm" and what was regarded as innapropriate. And because of this, I got into detention alot, for doing or saying things that I never knew were wrong.
But now that i've left school, all of that stuff is in the past. I am at my computing course now going for my level 3 National Certificate. I don't talk to the students, as they are all as narrow minded as those at school. But, I can concentrate better because it is only a group of 16, not as much noise.
When I get older and look back and see the once "high-school gangsters" as adults still working as a cashier at the age of 50, I will laugh.
Just think positive until you can get out of school. If you are old enough to leave, then if you want to, you should. Start a course on something you are interested in. Atleast at the course you will have people have the same interests as you, and you may be able to start, or join in with a conversation.
