This is horrible, I am so sorry this was done to you; you absolutely DID NOT deserve this and it is absolutely NOT your fault!
I have been where you are - trying to navigate in the aftermath of that kind of violent act - it is excruciating and terrifying, and extremely lonely. Please, please report this as soon as possible so that the evidence isn't lost and there is a better chance of this guy being arrested. I couldn't, and it has only made the years since so much harder.
You are not bad, dirty, wrong, or tainted because of this. It is not your fault
