All Stressed Out And No One To Choke...

I have done my best to raise my children right and it is so hard to sit and watch my oldest do a lot of the things she has done and is currently doing! I just want to scream! She keeps me worried, stressed out and I just don't know what to do anymore! She decided upon our return home from living overseas she would move in with her daddy and step mom. She said she didn't want to start over at a new high school where she didn't know anyone so I was hurt but I understood! Now lets however rewind time over the last year she has gotten way way way out of control and I can't quite figure it out. I taught her right from wrong and I have done any and everything I can think to steer her in the right direction so that she can make good choices and have a good life! However my teenager is lazy, sarcastic, foul mouth, selfish and I could go on and on! She was cussing at her step dad and I and her siblings before we left to come back to the USA! She never picked up after herself and acted if we owed her the world! She got worse when she hung out with certain children from school she got busted for shoplifting before we left. And oh yeah having sex great! Sneaking out of our home and what not lovely! She had stolen cigarettes from me, snuck alcohol she has done more than I ever hoped or thought to do when I was her age! Well now she is with her daddy and things haven't changed that much lets see physical fight with her step mom they both were smacking each other and pulled each other's hair out lovely! Sneaking out of her dad's house to meet up with a group of boys and so she could have sex with a 20 year old, smoking with her step mom, cussing her dad and step mom, skipping out on drivers ed to hang with a new boy! I swear at this rate I will be a grandmother long before I am ready to be one! I love my child yes I do but I don't know what to do anymore with her! I wish I could afford a boot camp or some kind of thing for out of control teens she needs to get her life in order! She has stated she wants to have a baby but heck look at how she is acting she isn't mature enough to make good choices for herself let alone another individual. She has admitted to her dad that the one time she got caught shoplifting wasn't the first time nice great! She lies to me more than she tells the truth! I want to trust my child, I want her to have a good life I just don't know what to do with her anymore! Her dad is about to pull his hair out! She isn't even living with me and she has me stressed out! Last weekend was her first visit with us since we moved back a month ago and she didn't want to come then cause she wanted to hang out with the newest boy but her daddy told her either go to your mama's or stay home so rather than being stuck in the house she came to stay with me boy I feel the love! And I don't' get it I am the one constant that has always been there for her done everything for her and she treats me like that! Her father has grounded her due to lying so she can't go to the dance she can't see her new boyfriend so she hits me up to come get her this weekend which I'm not doing cause of gas money and I have plans with friends and we live in different states now and she is going to just get over it cause I know the reason she wants to come so bad it isn't because she misses me or even wants to be around us it is simple she thinks she can have Internet over here and use my phone to text her boyfriend. It's sad really it's sad it would be different if I knew she just wanted to be here with me! I miss my little girl where has she gone and who is this stranger who has taken her place! My heart breaks almost on a daily basis! She swore she'd never be like this she use to watch those episodes of Maury with the out of control teens and she swore she would never be like them and well here we are at age 16 and is going the wrong way on a one way road! Lord help us all!
