Hey , hope your ok. Its a really sad story this.. im doing my best to stop taking coke and im dreadin my kids finding out about it.
Me and my partner cheated on each other and it brought nothing but arguments and its not nice on the kids at all.
All id suggest is, if your mum and dad are not willing to sort themselfs out. Think of yourself , work hard and get a good education. Be proud of yourself. And you and your sister help each other out.
Stay away from the coke please , your young and have your whole life ahead of you. I wish i was your age.
Do you worry about your sister while your at uni?
