These day are too hard

I've always been told that we'll always have obstacles to go through throughout life. My biggest obstacle was when i was eight and my family took in four of our cousins. So our family of six grew to ten, but our family connection shattered. These new kids were raised to lie and steal and they had no plans on changing that. They set up a reputation that none of us could change, the oldest, Amanda, she was socialable, and kind at times but then her attitude would strike your blind side. I was a freshmen and she was a jr. and kids i hardly know come up and tell me about her affairs with the teachers. Never once did she deny it. I knew what her mom was, a whore, and her father was a drug addict they both were. The twin boys just a year younger then me had their good and bad days. The oldest mike was violent and would always beat girls, no matter there age, the younger one james constantly lied and stole. the youngest girl Marie, she stole and lied as well her attitude and behavior mocked her elder sister. Finally Amanda left, she wanted nothing to do with us, my parents were trying to help her with college and she told them to fuck off she packed her shit and left. Mike just had a major melt down, he got in a fight at school started drugs and challenged me in front of everyone, no one knows where he's at now he just ran away. James and Marie still live with us and they enjoy it, theyre changing their ways but old habits die hard. It kills me that they now want to change when things are so shattered there's no chance of repair. They've lived with us for over nine years and now they want to change. That saying better late then never can't be applied to my situation
