But its very clear to me that you have walls and barriers around you. Your holding yourself back and people are avoiding you. I would think it would be easy to find a hobby or some kind of interest you enjoy. even if its outside of school you can make some friends. smile at people as they walk by, even if you think its a lost cause, try. by kind to the people around you, they could suprise you. dont expect so little of them.
People dont notice the unhappy people as much, human nature. you gotta come out of that shell, be a little loud. love yourself. you can do it talk to me if you need it :]
