Do you think im messed up.?

a few years ago i met this girl that i liked but i never made a move or anything. i tried, beleive me but she was never alone. three years after i met her she moves.:( and now ists been almost three years and im stillnot over her. everyday i log into my freinds facebook and myspace just to see pics of her. (for those who are wondering why i use his account, its because i dont use sites like those very often so wuts the point of making one of my own?) to those who tell me to move on or get over her, ive tried and i cant i keep seeing her everywhere. also i hear voices in my head but that because i listen to music too loud.
