Welcome to Beyond Blue and well done for finally telling someone - us - about your horrific experience.
I too was brutally raped when I was 17, and I know how awful it was for me to keep re-living it over and over in my head. It's a terrible thing to have to deal with and no woman, or indeed any person should ever be violated like that.
However, it's not too late to make a statement, if you want to pursue getting him charged. That too is a very big path to go down ....... one that I never did. Mainly because in my case I knew my attacker (he'd been my boyfriend for a few weeks before that) and he said he would kill me if I told anyone. Of course, he knew where I lived, so I was so incredibly scared. Many years later though, I did make a 'statement of no complaint' which basically means that it's on record, but no charges would be laid. I was just too scared to do anything more.
There are also counseling support services out there for survivors of sexual assault, which I would highly recommend you seek. Usually your local community health centre is a good place to start; if they don't provide that particular counseling service, then they would surely be able to point you in the right direction. And there's a number you can call - 1800 737 732 - is a helpline, and this website may also help:
On another note, I was also in a bushfire when I was 12 and for many, many years, it seemed to me as though everything always smelled as if it was burning or burnt. I felt as though I could smell fire for the next 5 years, thought I could hear it in the wind, and thought every sunset or sunrise was cause to flee.
Our brains are very complex machines, and trauma can do all sorts of things to us. Re-living the experience, without any tools to process those thoughts and feelings, is where counseling may help. You may not ever forget what happened, but you CAN live a better life.
And remember, it's HIM that did the attacking, NOT you that did anything to invite it. HE is responsible, not you. You have demonstrated your worth now simply by not keeping the secret any longer. It's here on Beyond Blue.
I do hope that you get yourself some help and support to get through this, and get back to living a life that doesn't involve jumping at shadows.
Take care. I'll look out for your reply. xo
