Only thing to add here is opt for a paper bag rather than plastic. I'm sure cops will take over and transfer it into the proper bag, but the lack of air in plastic can cause mold and decay of the clothing and any potential DNA on it.

I agree with everyone else. Even when I have blacked out there's usually a fade in and out before hand. Definitely go in babes and see if you were drugged and get a rape kit done. I know it can feel shameful or embarrassing. Though trust me from experience, not doing or saying anything is worse.
