I’m (F26) keep getting PTSD flashbacks

I guess I’m just feeling lost. I experienced being secretly filmed by my step dad when I was 18 in an embarrassing and demeaning manner and found out about it when I found the camera in my bathroom. That being said it’s been 8 years and I’m currently on medications for anxiety and depression after another man exposed himself to me on the street, but the medicine has been really great and I’m proud that I reached out. I’ve calmed down a lot through meds and don’t feel as anxious around men. But recently for the past couple months I keep having flashbacks of him and other things that trickled down from this experience like hypersexuality and just putting myself in really bad and dangerous situations. Sometimes when I close my eyes, it all comes back. But i guess I just assumed symptoms of PTSD would all go away through medications.. i just I feel confused and lost and I didn’t know where to say anything about this and sort of like in a way a failure, so I’m writing it here.
