Me vs. Her

I have struggled for so long now with Alyssa.  I don't know what to do with her anymore.  I have grounded her, I have added extra chores, I have prohibited her from seeing friends, talking on the phone, taken away her phone and her computer, blocked access to any internet that she could possibly get a hold of but yet ... she still defies me.  I have to lock up Brittney's clothes so that she doesn't wear them.  I have to hide money and cigarettes so she doesn't steal them.  I have to have my son lock his door at night so she can't intimidate him into letting her on the computer.  I am at the end of my rope and just don't know anymore.  Last night she didn't want to come home ... we kept going back and forth with each other through text because she wouldn't answer the phone.  I ended up having to call the police.  I had no other option.  It hurt me but what else is there left for me to do.  I ended up pressing charges against her and now we will have to go to court so they can decide what to do with her.  Brian said that they will probably ask me what I want done.  I don't even know anymore.  I feel bad but at the same time maybe this is what she needs.  I'm just kinda lost.  I love my children so much and try to do what I can for them ... but I can't help them if they don't let me.
