Should I tell my parents?

When I was 11 years old, my best friends dad molested me. I was so terrified of him and he threatened to hurt my mother and I if I spoke about it to anyone. Then when I was 14, a friend of my dads raped me. I never told anyone about it until roughly a few months ago and it felt great to finally not hold it inside anymore. But more and more recently I have been thinking about it all and I want to tell my mom. But I am afraid of what will happen if she tries to go to the police or to confront the men who assaulted me. Even if she goes to the police, they can’t do anything because I would have had to report it in a certain amount of time. But lately people have been making so many “rape jokes” and every time I hear one I want to scream and cry and hit them for being so fucking insensitive! But I am also afraid of what people will say about me... The first person I told was my ex and now he proceeds to call me a whore to all his friends. I just really don’t know what to do.
