Girls are soooo difficult at this age! I have 1 daughter and she disappeared from age 13-18. The kid I was left with during those years was a stranger. However, we both managed to wade through all the muck and come out the other side. I am happy to say that she is a lovely, responsible, and loving daughter today. The best advice I can give to help weather these difficult years is to always leave the door open for communication. No matter what, she needs to know she can ALWAYS come to you. I promise it will be the best thing you can do as a parent. blessings and good luck!
