Confused, blank memory

So I have been molested at a party when I was drunk at age 16, I remember saying no at the start of the night and walking away from him and then was told the next day what had happened. I knew that it was true from the feeling my body got when I saw him out. I always wondered if I was touched as a kid and recently during a therapist appointment I was explaining how I loved seeing my mums aunty and then having one memory when I didn’t want to go to their house at all and wouldn’t let myself be alone with the uncle. Ever since then I have hated him and had break downs every time I see him. My body reacts the same as when I saw that guy who touched me when I was 16. There is more to the story just my issue is I have no memory just a blank. Anyone else have this happen to them
