How do i get over an accident?

i was in a car accident in 2006 while walking home from a football game and i was crossing the crosswalk legally and i had my ipod on so yeah i looked both ways and in thd far off distance were two cars and when the light turned red one car stopped for me on the last lane farthest from me and i kept walking because it stopped (by the way it was 11pm after a football game, i was alone walking home not drugged out or anything) so i kept walking and i look up and the light turned green like a block away and i looked at my ipod to change a song...and i heard a car speeding up and revving and stuff but then i thought thats what cars do and then they slow down and stop for the crosswalk but i looked up to see where the car was and i saw the headlights and thats it. i remember bringing myself up and like my shoes had fallen off and my ipod and wallet and just everything. i was about 30 ft away on the floor half of my face literrally skinless now bleeding my bones near my wrist had broken skin and my bones were popping out of the wound. My knee and legs were swollen. so the car drove off the car iun the farthest lane wasnt paying attention and didnt see the car that hit me, they called the police and all . and another car drove up and tried to chase the other car, but lost them. so yeah now 2 years later on 11/17/08 it will be 2 years since then.. b ut is something wrong with me? like that year i was like saddened by the event and i didntg feel nything like i acted so over the situation at that time (partly due to my vicodin, which i became addicted to for about a month too) but now im afraid of cars... i hate crossinf crcosswalks and my friends always joke about it and when i try to be serious about it they think im kidding due to the fact that i was always saying that i was fine. Since then i still feel em pty on the subject. like am i supposed to be feeling sad or anger over the fact that the driver was never caught or what? and i feel like i owe this day my attention like i dont know sitting at the intersection i was hit in, like somethign that vwill bring closure to possibly something im not admitting to? anyways please help me with this its been bugging me and last year i had nightmares of the accident for a week before, anmd the week starts tomorrow!(monday) help!!! im 16 now, 14 then
