I told my dad, and he shrugged it off and said she'd come around. It's been a few years and nothing has changed. My sisters tell me that she won't even acknowledge their presence when in the same room. I've tried to talk with my dad about this, and he says it's between him and his wife. Is there anything I can do for my sisters?
Answer: This is awful. My first thought is, do you have any relatives who would open their hearts and homes to your sisters? Or is there another responsible adult in their lives you can approach?
The second thought is much harder and riskier, since it involves your becoming their guardian - and essentially giving up your young adulthood.
You'd obviously have to weigh the benefit of the home you could provide, which would be immature and financially unstable but loving, against the benefit of their current environment, which is stable but loveless. However, there would be no harm in your just exploring that option, if you're willing, to see if it's even realistic - financially, legally, emotionally.
You likely have access to counseling services through your college. Please make an appointment either way and talk to someone about what's going on. Also, try Childhelp (1-800-422-4453 or www.childhelp.org). This is a great source for a reality check on whether your sisters are better off staying put, and how you can help them.
Obviously both of these ideas rest on the assumption that your father would surrender custody, but that doesn't seem like a stretch. He's allowing his kids to be emotionally abused before his eyes; I don't see him fighting to keep them at home, unless you spur an epiphany.
Even if there's no practical way to give them a more welcoming home, your loving, consistent presence in their lives can be the breadcrumb trail that leads them out of the woods.
