Does any one understand?

I find myself here, feeling down. I've been searching all morning for someone to chat too! I'm 32 and for many years have coped by just "not thinking about it" but recently have started to have dreams that keep "it" on my mind.
I feel that maybe the time has come to go to the police but i don't know where to start, i'm scared of what that will bring, have i left it too late, will my family fall apart?
I just guess i need someone to help me in the right direction so if any one can give me information about support groups or better still an online chat Funny thing is i'll probably be o.k tommorrow......Thanks Karen
