I’m planning on Leaving my home for good as a 16 year old.

Hi everyone! Just like the Title said, I’m planning on leaving my elderly home for good, My household is toxic, Violent and disgusting, My stepfather abused/assaulted me ever since he came into my life at the age of 4, And my mom chose to stay with him. This scarred me for life and I’m willing to look for help, But since this is stil reality till this day, I can’t think about nothing else but leave this place. So today I’m packing a backpack with clothing and toothbrush and I’m gonna leave. I can’t stay in this toxic household. And I know what people may think, Why don’t u just look for help? In the country I live in, If u look for help and manage to get into the foster system, The parents still have the right to come and see u, I don’t want none of that. So what I want to do is take the first train out of the country (I live in Europe) and go to Spain. A good friend of mine lives there that used to live next door, And his parents are willing to help me. I want to begin a new chapter of my life and leave everyone behind, It’s hard but it’s the best choice for me, Does anyone who may have ran away in the past, Have any advice for me?
