It sounds like you've been through something really awful. Nobody has the right to do that to you. I think you should tell your parents, you didn't do anything wrong, and they will want to know and help you.
Also, I think you may get more appropriate responses if you post this in the Serious forum
. What has happened to you isn't nothing, and you can't just brush it away... I realise this could be difficult, but have you been to the police? Have you told anyone about this? You don't deserve to struggle through this on your own love x
