A girl that i love... but i dont know?

ight... this is a pride swallower. I have really liked this girl for a long time... as in like the first time i saw her 3 years ago in 8th grade. she was getting recognized if front of the school for being a honor roll student i think. i didnt know who she was or anything about her except the fact she was the most beautiful girl Ive every seen and i got this amazingly happy vibe from her. i never thought i would see her again. crazy coincidence, i got to know her much much later on though a extra curricular thing i got heavily involved in for my school. ive been heavily involved in this program for 2 years and it seems that even though i spent all that time around her i still feel extremely unconfident around her, like i'm never going to be good enough to be with her. i struggle from low self confidence, i think its mostly cause from the severe acne i suffer from. i have also been asked out several times but never by anyone i really have wanted to go out with. a lot of my friends have wondered why ive turned down so many girls in the last year and ive never told them, but its because ive had some delusional idea that maybe she would ask me out or that maybe i would gain some self confidences and ask her out myself... ya..... sad .... i know ...... what makes it even worse is the fact that ive never told her i even like her. i have even tried forgetting her to the best of my ability, it never seems to work...... what am i to do.... :(
