We went through exactly the same thing with DD#2. She is 5 years younger than #1 so, in many ways, was doing everything on her own, similar to an only. Extremely smart, pretty, & head strong (grad HS at 16) she faltered in self confidence. She went through some very scary phases including green hair, drugs, piercings, cutting classes, and even a tattoo. Not unheard of but, at ages 15 & 16, definitely not the norm in my family. She broke down crying one day and told me that she needed to talk to someone outside the family. We researched and found someone professional that she spoke with several times. However, this person didn't seem to "get it" (my daughter's words) so we searched some more and ended up with one of our Pastors. He did wonders and now, at 23, DD is happily married, finishing her degree, and working part time for a church as assistant youth director!!! Such a big turn around and such a blessing! I guess this tome is my way of saying, <b>Hang in there, listen to her, and make sure that she is comfortable with whomever you find to counsel her.</b> I wish the best for you and your daughter. God Bless!
