Is this normal emotions? (tw sexual assault)

So this past week i was Assaulted, since then ive been having a hard time going to sleep, ill shower bathe try to relax at this point not even sleeping pills are helping me. The thing is i dont feel scared, angry, hurt, like i feel nothing. Im just empty. Idk if this is normal (im sure it is). I was almost expecting to feel scared, weak, embarrassed u know all the things that u hear victims talk about. I dont feel any of that. Which is in a way scary to me. I get flash backs of what happened and i feel nothing, i think about what i could have done differently and again feel nothing. Not even a tear.

It almost makes me feel like im imagining the assault or making it up in my head but i know for a fact it happened i have the bruises and scratches all over me.

Is this normal? Is this ptsd? Whats going on? Why am i not feeling anything? Its almost as if my mind is completely wiped clean of how to feel emotions. wtf is wrong with me!?!?!

How is it that something so traumatizing, doesnt have an effect on me? How can i tell anyone what happened if theres no emotion or fear of what happened coming from me? How could anyone believe me if im not feeling any emotion from what happened?
