I know this sounds real wierd but please...?

I am 18, with a young son called Damien who's 3. I had my son when I was 15(I know!) with my girlfriend Sam. We were at my mum and dad's home in Russia, when it went on fire. I lost my mum,dad and girlfriend. I rescued my then 12yr old brother David and my little sister Anne-Marie, then 5. We were sne tot live with a woman who we had to call Madam in Romania. This was our parents wishes. But she is pure evil. She beats my brother, makes me and him work in a mine and makes my sister work as a servant. I am worried the dust from the mine could harm Damien, as I have to take him down with us. I need advice and has anyone else ever been in this position. I know it sounds wierd.
