<human>: Some people in this world are fucking parasites, who thrive on the hatred and distress that they cause in people. My 'father' was one of these parasites. I have 2 siblings, an older brother and a younger sister, I noticed from an early age that he treat me different. Whenever I would do something slightly wrong he would hit me, I would often end up with painful, tender bruises caused by his hands. I thought it was normal at first. I would hide in the bathroom for hours just to get away from him, it was the only room where I could lock myself away. It happens to everybody right? I found out over the years that it didn't. By the time I was 15 I'd built up the courage to shout back, we'd argue on a daily basis until I locked myself up in fear that I would punch him again and again until he was dead, I didn't want a criminal record. When I was 16 I said to his face that if he ever laid a finger on me again that I would call the police. From turning 16 I wouldn't lock myself up anymore, I'd keep shouting, aiming for him to hit me so he'd be taken away and me and my mum we're safe, he'd constantly bring my mum down too, she was scared to death of him and he made her feel like she couldn't leave because she couldn't cope without her, even though she is the strongest person I've ever met. In September 2012 we finally got away from him. We we're finally safe. We never had to see him. In February 2013 my Nan, his mother, was rushed to hospital, during the time we visited her he'd be there, the combination of seeing my nan slowly getting weaker and seeing him again, acting like he'd done nothing wrong drove me into deep depression, which I'm still suffering from and caused me to break up with my girlfriend of a year and 8 months almost a year ago.
