iam so sorry for the anguish you are going thru. I have to say I have never used drugs and couldn't even imagine what it is you are going thru. when you have children involved it makes things a lot tougher on you I imagine. I am so happy to hear you are taking the step to get clean. you will be back to that person in the pictures and you will be so glad you did. your children are your reason for living. remember that.
my thoughts and prayers will be with you.
