recovery is long and hard process.
Good thing is that you found this site. Here you can find a lot of information how to deal with CSA (Child Sexual Abuse).
It would be good for you to first explore this site in detail, to see what other people are writing, who is who and to check some of the professional reading that could be found here.
You must be careful because you are very young; do not give your personal information to anyone. Also maybe it would be good to contact some of the moderators and ask them for advices and security tips.
PS. Abuse can happen to anyone, for example I was abused by one older boy. I still have scars many years after and I am not comfortable to speak about it to other people. The secretes of successful recovery are in your will and determination to success and overcome all obstacles that are bothering you. I am wishing to you good luck on this hard path.
