I'm so sorry this happened to you. It sounds very scary and I want you to know you are not alone.

I have had multiple sexual assaults happen to me (sorry I can't say victim or survivor yet, I really don't want to say assault either but I'm going to listen to my T and call it that). And yes, I experience extreme guilt. I blame myself for being assaulted more than once, I blame myself for staying in the abusive relationship, I tell myself it was not that bad. That's very common and you are not alone. You don't need to feel guilty. You did not do anything wrong. We all respond differently to assault and there is no correct way. Somebody did something wrong to you and you did not deserve it.
