What should I do? Rape Victim.?

When I was little I was raped upwards of 10 times by a boy in high school, while I was only in grades 1 through 3, what should I do. I have known for a while that I have been a victim of rape, but I'm not sure if since it took to long for me to find out what was actually being done to me if I should press charges or not. I mean could I even win a case that happened so long ago? I have no clue what to do, please help.
