I don't care about anything bad that happened in the past I feel like I can't sympathize with people?

I remember, one of my earliest memory's, I was molested by my cousin. I was away from my mom for 5 years of my life when she was on meth never saw her once, many family members have ped away from drugs and other things, it would seem I would be somewhat disturbed by everything that has happened in my life. But no, I just don't care about any of it, and I don't know why. I can't tell people that I feel the same thing, cause I don't feel anything about these memories. Or any old memories for that matter. Why is this?? I feel like a freak...
