I get the strong sense that your dad is dealing with a mental health issue. I get the strong sense that you are as well. I cannot put my finger on it, and it may be a result of the abuse you've been subjected to, but you definately need help sooner rather than later. You are living in an unhealthy environment ...... I don't know exactly what's going on but I do know you need professional help and so do your parents and children. Why don't you call an abuse hotline and get some advise?
