I feel for you, too. husband and I are on the same page this time, a contrast to the initial. If not for him (and he feels the same way about me), no one in our families truly understands. To them, it's "you've been down that road, she's hurting you all and us again, just detach and move on". Like you all know, until you have been in these shoes, very easy to say!! We have good/strong days and bad/weak days, it is SO hard to watch your flesh and blood mess up, lie, etc., when you know everything they need to help themselves is right there. Your heart just hurts so, so bad, you can't explain it. Some days I ask why is this happening again, why can't difficult child be a "normal" 25-year-old mom?? It does just break your heart.
So sorry. ((hugs))
