It’s possible that you feel dirty, guilty, ashamed, angry, etc… You might feel abnormal or desoriented, have the impression that you are going crazy, and you may feel like no one can understand you or even believe you.
All those reactions are absolutely normal but experiencing sexual assault isn’t. No one is guilty when being sexually assaulted. Indeed, there are no reasons to justify this crime. Only the sex offender is guilty and 100% responsible.
