Have I got PTSD?

Been raped a few years ago, sexually assaulted a few days ago. And now I keep questioning why I went there. If I didn’t go it wouldn’t happen. Maybe I shouldn’t have been drinking or even talking to his friend. If I sat there silent it probably wouldn’t have happened?

I randomly start feeling sick and thinking about it and it’s like I want to cry but nothing is coming out. I feel numb at the thought of it. I feel shaky and I won’t leave the house because everyone has seen that video. the thought of walking to shop around my area makes me want to cry. I feel so ashamed and embarrassed and degraded. I haven’t been eating properly maybe 1 small thing a day like a few fries cuz my moms been making me and a pack of crisps. I’ve been really tired but even when I sleep I’m still tired.

I’ve got some anti depressants off the doctors but I read things like this can cause PTSD aswell.
