Too late?

I am 15 years old and about a year and a half ago I was inappropriately touched by a male family member.. In the genital area. I never told anyone because I thought I would get in trouble . I don't know why but I never told anyone. It's always on my mind and I feel extremely uncomfortable whenever he comes over our house. Is it too late to tell someone? Because it's breaking me down inside I can't keep it to myself any longer 😪
Is it normal to feel unsafe and very uncomfortable around that person?
