We always tell our daughter that we will help her when she gets help and is serious about it. But, she's gone so far down that she has LITERALLY nothing left, and a felony conviction, so getting a job will be harder...she's homeless and has the clothes on her back, that's IT.
So, by helping her, we mean possibly sober living or rent for a few months to tied her over, AFTER treatment. Medical insurance IF she can't get it on her own, and the like. It doesn't mean supporting her forever and letting her laze around and not be productive, but giving her a stepping stone, as I know it will be difficult when she decides to get well.
I think, if they are doing all they can, EARNESTLY doing all they can, then helping them really is helping and not enabling.
