Please take care for yourself Sven and look how to avoid your father and uncles if there is some alcohol involved or anything that could spark their violent behavior and abuse. They are bunch of toxic persons and I'm sorry to say it but other kids could be victims already there
Anyway your personal safety is priority, I know how difficult could be for us survivors to start thinking on own issues and how to tackle so many on going problems. We have problems with our personal borders as they could be destroyed by abusive persons. So we have somehow to start building it, learning how to manage people around us and how to stop others to be hurtful and violent. It is very difficult task and many times only what is possible is to leave abusive environment and stop all communication with abusive persons.
Also be aware that we survivors are many times very hard on ourselves. We are taking all blame from abuse on ourselves and in such way negative self image is built inside us.
So it is good to exercise proactive and assertive stance acknowledging something positive that we all have in us as counter measure not just to focus on the worst parts as probably many of us are doing by inertia.
So here is the link to material called: "first steps to get help" with some affirmations at the end; it has been written for us survivors and it brought big change for me when I read it first timehttp://www.affirmationstherapy.com/aff_first_steps_help.html
I'm very happy that you are with us here, you are very sensitive and honest and I'm sure you are great person.
We all here are to give support to each other so be acknowledged that you are not alone.
