Into the unknown again

It is a sad day...today we called our adoption agency to tell them we will not proceed with this birth mother.   To make a long story short, last week we found out that the birth mother tested positive for cocaine during her 7th week of pregnancy.  This past week and a half we have been working with our caseworker to figure out the truth.  We even scheduled her for a drug test on Friday that she did not go to until the next day.   To our utter disappointment, we realized that she has been lying to everyone the whole time.  Come to find out, she has a problem with cocaine and has used during this and other pregnancies.  Even though she wouldn't fully admit to it, we highly suspect that she is also using marijuana, smoking, and possibly drinking alcohol.   She was telling the doctor one thing, our adoption agency another, and then us something totally different.   Because of this she totally lost our trust and we don't know where the truth ends and the lies begin.  Our hearts are broken, but we still pray for her recovery and the health of the baby.  Hopefully this will be a wake up call to her and she can get her life straightened out.  I'm not sure what hurts more, being lied to or losing this baby.  In the meantime, we are back to square one with broken hearts and deflated hope.
