Am I Crazy or did it really happen?

Hello, not too long ago a therapist helped me realize that my father has behaved inappropriately towards me in the past. My father used to take pictures of me, and tell me to pose "sexy" and I hated it. I was still fully clothed but I hated it nonetheless. We used to play tag while naked or he'd touch my thigh or kiss my neck. This occured from a very young age until I began puberty, in which he stopped paying attention to me altogether. I always used to feel these random waves of disgust, in the most random of times, like I was the most disgusting thing in the world. I held that in until I finally told my recently therapist but I'm kind of afraid that I am maybe exaggerating or blowing everything out of proportion because I don't remember much but I still live with my father and he's the only one who can provide for me. I want to confront him but I'm beyond terrified. What do I do? Am I making this up or not?
