I am so sorry your parents have put you into this situation. Having nieces your age and knowing how they behave, you are definetly a very mature person, and seeking help is very good. The first thing I want to say is that God didn't put this on your shoulders (your parents did,) He will give you the strength to continue and come out successful. The rest is just advise that might help or that you can try. Get your brother and sister to help you. You three are in this together. If your school has counselors talk to one of them and try to get your parents and you kids in a meeting and discuss your feelings and desires for the family. I'm not sure if sitting down with your parents alone might work, but if you bring a professional they might be more willing to listen to what they are doing to you and the other kids. Talk to your mom and give her her place as the mother. She's going through a very difficult time with her husband; however, she's still have responsibilities. The most important responsibility is to take care of her kids, you guys are still there and you guys need your parents, you need the protection, you need the assurance that someone is there for you and someone will look after you. Be yourself, be strong and have fun, you are still a kid. Keep seeking for advise, get other family members involved, do you have grandparents? Aunts? Ask for people support. Good luck and I'll be thinking about you. E.
