How can I tell my parents and should I have gone to the police

Two years ago this happened to me and I still get the nightmare of it:

Over a text, we had arranged to meet. For him to pick me up. My friend was sleeping over so I figured I had an alibi in case my parents questioned where I was. We were sitting out in the trailer talking about the world and all of its problems and religion and politics, and I didn't hear a word of it. I just kept checking the clock, waiting for the clock to hit 10. I didn't need for him to text that he was here, I could already see the blinding LED lights of his truck through the curtains on the windows in the trailer. I stood up and told my friend that I would be right back, not to worry, not to tell my parents and that I’d be back in a half hour, and not to worry again. And I left her in the trailer by herself sick with worry, I know, best friend of the year award over here. I could barely see past his high beams and the light bar glaring over his new truck. And with that, I got in the truck. We exchanged pleasantries and decided to park in the same place we did the last time. When we got to the end of my road he put his hand on the inside of my thigh and told me to get closer, I did. He drove to the same spot and parked, he turned the truck off and reclined the driver's seat. All the detail after this are a little blurry but I remember him grabbing me by the nape of the neck and forcing my mouth down on him until I gagged a little. I pulled away and he told me to get in the back of the truck, so I did. He got out of the truck and was outside for what seemed like forever, on the phone I think. I sat in the back and waited. He opened the back door and got in the truck with his pants down. He got on top of me and we made out while he pulled my shorts off, my panties along with them. He put in so hard and fast that my immediate reaction was to tell him to stop. I kept telling him it hurt and to stop. I remember him putting his hand on my neck and telling me to be quiet. I continued to tell him to stop and I tried to sit up. His hand tightened around my neck and I felt the back of my head hit the glass window behind me, over and over and over again. It felt like every time he thrust he punched my head harder and harder into the glass. I couldn't breathe. I tried clawing at and hitting his arm to make him stop but it seemed to only make his grip tighter and tighter. So I stopped, I gave into the fact that this was happening and there was nothing I could do to stop it. I was powerless. He finally released his grip on my neck, I think finally when he felt my body go limp and I stopped resisting. I gasped for air and turned around trying to find the door handle, but it was dark and the door was locked. I knew he hadn't finished and I wondered if he would continue. I think he waited till I stopped coughing before he pinned me against the door and held my arms against my back. After he grabbed my arms all I can remember is the feel and sound of his breathing on the right side of my neck. I can't remember how long I was gone for. He must have finished. He let me go and got out of the truck to put his clothes on. I didn't even know where my shorts were. I don't remember putting them on. I remember laying there on the cloth seat of the back of his truck, numb. Everything hurt and I couldn't think straight. I heard my phone ringing and I didn't know where it was. I think he handed it to me or I found it, my mom said something when I answered, I don't know what it was, it sounded like she was crying. I just kept telling her I’m on my way, I'm coming. He took the phone out of my hand and hung up. I don't remember the drive back. I remember him pushing me out of the truck at the end of my road and somehow landing on my feet.
