Please know that my heart breaks for you tonight....
I know how you feel
I truly understand the desire to isolate...I want to advise you to do differently but it really would be a case of "do what I say not what I do"!
Your daughter is sick and she cannot help her actions (yet)
that doesn't mean you have to accept or get sicker with her but it does help to know that she too is suffering (if possible perhaps even more than you are tonight) and does not want to be on this path
be gentle with yourself.....
you are a loving mom (I remember your post about cooking dinner at the recovery house)....
try to say a prayer tonight and hand your daughter over to her HP
I wish I had the words to heal a broken mother's heart
please know you are not alone and please allow yourself the support, love and friendship that awaits you here at SR
