thank you for sharing here with us today. it's difficult sometimes to acknowledge our straying from the path we know is best for us. when i read your post i agree with lenny and capp. the other thought i had was "success begins with a single step". you've taken that step here. your honesty will provide you with the courage you need. life problems (your daughter in this case) can often times lead us in the wrong direction as it takes the focus off what we need to do first. a thought-you will be better able to help your daughter as you wish to do if you are drug free. she is a very fortunate lady to have you as a mom. by being responsible to "self" you will be able to help her too.
once again know that you have taken the first step to become whole again and honesty is the key.
