Feeling scared

6 years ago when I was a junior in high school I was raped. It took me a really long time to even come to terms with what happened. I was 17 at the time and I had never had a bf and I had never even had my first kiss. This guy kept asking me out and would not take no for an answer. He would ask me everyday and my friends kept pressuring me and telling me I need to go out and just have some fun for once. So I said yes to the date. He took me to a park in an empty parking lot and that’s when it happened. He forcefully kissed me. I pushed him off and I said no. He then forced himself onto me and I said no. He was way bigger than me and I couldn’t get him off. I was scared and eventually froze. I honestly block it from my mind. I said yes to that date and I said yes to him picking me up from my home but I did not say yes to sex. It took me a really long time to accept that it wasn’t my fault. I’m in a happy relationship now and I’m doing really good. I never told anybody because he was well known and I didn’t want to go through all of that. Today my bf and I went to the gym and I saw him. He didn’t recognize me but after all these years for the first time I had seen him and I froze. I was shaken up and in shock. I didn’t know what to do. All day I’ve just been off and I am paranoid. Every truck that I see I feel this fear because he drives a truck and everything comes flooding back to me. That day and the way I felt. That shame and guilt.
