Any victims who have tried therapy?

Around 2 years ago I ended things with my abuser of 3 years. It’s been so long, but I still feel the affects of the traumatic things he put my through. My school has free therapy sessions so I’ve thought about trying to go, but the idea of going for something that’s happened over two years ago kind of feels silly. I’m just wondering what they might be able to do to help me. Anyone have any experience going to therapy for this specific issue?
