oh my god, only 3 weeks ago? 3 weeks is nothing in terms of recovering from such a trauma. whether or not this is something you could call OCD or PTSD or whatever, i really think you should get some help, from a rape crisis center or something. if you're too scared to go then just call them.

you should absolutely feel free to nag the police. a rape case is not like getting some car stereo stolen, it's at the top of the pile, or it should be. you call and nag as much as you want, or get the crisis people to do it for you.

wait, the people living with you are involved with this? can you get out of there? i think you should. I don't know whether or not it's likely that they will be violent towards you, so don't take this as saying your fears are justified. but you are extremely and JUSTIFIABLY uncomfortable, and you should do WHATEVER you think will make you feel better (and doesn't hurt anyone) and it it doesn't work try something else.

that's not the usual advice for OCD, but OCD is about unreasonable fears, and it is by no means clear that you are being unreasonable. you can't judge because of the trauma.

i'm sorry for the caps but this is really worrying to me. please keep in touch. i'm traveling tomorrow but I will be checking in on this.
