The past 5 months

Today, my son who is 24 (I will refer to him as "T")  has been on my mind. I do not know whether he his dead or alive, in jail headed to prison or on his way to buy heroin some where...  My heart breaks for him but at the same time I am too exhausted and heartbroken to spend any more time trying to track him down to find out.  In fact, I'm to the point that I doubt I will take his calls any time soon.  Last week he told me he had just done something really bad and that he knew he was going to get caught (I told him I didn't want to know what it was) and then he told me he was going to do something else that was going to be bad.  I have a pretty good idea of what that is and it involves drugs.  Six months ago he and his girlfriend (I will refer to her as "G") were battling addiction to Oxycontin so I moved them back with me (4 states away) so they could go to treatment while I took care of their 4 year old daughter (the love of my life) and within five days, she is overdosing on my living room floor on "china white" and he is having to confess to the paramedics what she took in order to try to save her life!  They couldn't find Oxy when they got here so a total stranger off the street sold them this crap!  After her trip to to the ER she promised she would never ever do drugs of any kind again.  The doctors and nurses told her "BS as soon as you start feeling better in a day or two you will go do it again"  I am SO stupid that I believed her.   I have put up with this out of T & G for six loooong years!  Over the next two weeks, between December 16th, 2011 and January 1, 2012,  these two went on to rob our house of everything of value that they could carry out the front door without us noticing, including my deceased mother and grandmothers jewelery not to mention mine, my husbands personal property, my brand new shoes and scarf (I never even got to wear) and my husband and his employers tools.  Every day we find something else GONE still after all this time!   BUT that's not the worst of it...Once we found a couple items missing, they denied it but  we told them to leave our home and within 2 weeks, on Friday, January 13, my precious 4 -1/2 year old granddaughter is  taken from a motel room by child protective services.  She is still there after over 4 months.  Why can't I have her rather that her placement in "the system"?  Well, that is the next story to come and my lessons learned - the hard way!  My husband has a past history of domestic violence charges.  Are my kids still doing drugs?  Is my husband still abusive?
