My dad are really pissing me off! You see, I have this step sister and my dad treats her like shes this baby. He never pays much attention to me anymore and its like I don't exist in his life anymore. He's always spoiling her with heaps of stuff. It makes me feel sad cos it feels like he doesn't love me anymore. I've been thinking of running away to my mum's family but I don't want to hurt my dad's feelings. I mean, he wouldn't notice or care if I did run away. What should I do?
