Friendless, I need help.?

well, i'm a sopre in highschool that has no really-close friends (the ones who you sit with at lunch). i've been new to this school ever since freshman year, and still haven't made any close friends of my interest or gone to any of the dances. Even in middle school i was kind of the loner who got teased and name called here and there. I always see people getting invited to hang out after school, on the weekends, or go to parties, and i always wonder what it feels like to be invited to something. Even on my birthdays, i barely invite people, because i have no one to invite, besides family but that doesn't count. Typically i am shy, but i am in clubs, sports, and I'm always open to conversation, greeting people, and even really funny at times,etc. and (not to be arrogant) but i am pretty good-looking and well-dressed. but it seems that no matter what i do, I'm always unnoticeable and unconsidered by people. Is there something wrong with me? what am i doing wrong? Thnx for listening.
