I cant slepe at night and drink to sleep ig

Im 18F – I was SA abotu a month ago, I was forced to report it to the police however chose to not take action, I have also since found out his name which I have not told them becuase I dont know his last name.

Anyways, I find it so hard to sleep at night im talking i have to either have every single light on and be bundled up in blankets, i usually dont get to slepe until 330-430am at the earliest, Im so scared to sleep i just wake up shaking and sweating and now i sleep during the day when i can. I dont know what to do, I have no one to support me through this, Ive been drinking every weekend, straight vodka to cope and pass out alseep but still wake up shaking and sweating Im so scared. I dont know how to help myself much now, ive just been hopign that the nightmares go away.
