How far is safe enough?

My grandpa is a evil man. He maked cp with me from age 0/4 to 16. After my he in 2016 and my grandma last year died my mom and I where cleaning the house. I told my mom that I would deal with the usb sticks. I was afraid of what i could find but nothing could've prepared me for what I found. 400+ hours of video's 300 hours of me as a child being tortured, sa'd everything. More than 20 man saing me as child.

I took the usb sticks to the police how didn't believe me for years. The police man was crying.
Since than I got stalked again, 1 man stabbed me saying "this will learn you" a oftet man just sad me again.

I want to move, I have a house 54km from here at 5 jan. But I don't know if that is far enough? Should I go to a other country?
