Hi, Rachel. I know how painful it must be to see your older sister act so terribly, but it's really not your place to keep her under control. That's your parents' responsibility, and their responsibility only. What you can do to help is stay out of trouble yourself, keep your grades up so that your parents don't have to lecture you or attend parent-teacher conferences, and help out around the house so your parents can gear their attention towards your sister. I wish you luck! – Courtney, 14, New York

I understand what you’re going through. Sometimes it’s very hard because you want too help your mum and dad out. Have you tried talking too your sister and helping her to realize what she is doing and how you feel about it this? It might help her to understand what she is doing is wrong. The way to help your mum and dad is too try and talk too your sister for them. If she does not listen keep trying. You might be surprised. But she might actually need a friend not a sister at the moment. – Jade, 16, United Kingdom

Rachel, I know it’s hard to watch your family members go crazy right in front of you. My big brother did that – running around drinking and smoking and doing things that would probably have put him in jail if he’d been caught. My parents went nuts trying to control him and it sure didn’t help things around the house. But you can’t control what your sister does, and trying to do that will just make you crazier than she is. So don’t try. What you can do is keep control of yourself. Do well in school, keep your room clean, do what your parents need you to do. If they don’t have to worry about you, that will leave them free to try and take care of your sister. But TALK TO THEM. Let them know you’re on their side, and you want to help them as much as you can. And that’s really all you can do. Good luck, and let’s hope your sister grows up soon! – Mallory, 16, Virginia
