First time talking aout it and scared

I have never talked about what happened to me and I am scared to talk about it. I just turned 19 and i know this was a while ago but all the memories that I have buried for so long keep coming back and I hate having the images and memories.  I have not talked about this to anyone since it happened.I just dont know what to do. I cant talk to my parents and I dont even know where to start its suck a hard convosation to have even at this age. I have the fear that when I tell my BFF or boyfriend how they will react and leave me. It seems easier to just keep it a secret but yet suffering is no fun either. Im stuck and dont know where to turn.
