I agree with DDD on this one. I know you're hurting a lot, Nancy, rightfully so, and I'm so very sorry you have to go thru this. I'm about at a point though where I think we (parents) have to hurt more than the difficult child in order for them to hit bottom, quit feeling like we'll always be there to bail them out, and finally realize that they are responsible for their own futures, consequences and all. That "doom" that you feel is you realizing the difficulty and potential problems of all this- because you are wiser and a more experienced person than your difficult child. If you jump in and bail her out, - if we, parents, always jump in and "save" the situation when 'we' feel/see the doom, the difficult child never sees the doom themselves and never gets the wisdom and experience and never sees any reason to. When I look at it that way, it seems inevitable that parents have to feel more of a "hitting bottom" than the kids do, if we are to let them learn their lessons. And that just hoovers because it hurts like heck. But in my experience with my son, bailing him out or trying to save him from digging himself in even deeper sure doesn't seem to work- that just seems to reinforce a message that "mom will jump in".
All that being said, I don't know if I could, or how I would, deal with it if I thought I had a grandbaby on the way, and thus leaving an innocent baby in a mess. I guess if I felt it was the worst case scenario, I could call dss/cps to make sure the baby was taken care of but geez.....how much faith I have in them, I don't know.
I remind myself time and time again (I have to for my own sanity) that until difficult child cares about himself more than I do, until he cares about his future more than I do, until he cares about doing what is constructive and being a good person more than I do, any action I take to lessen consequences his actions have caused is serving only to enable him and increase any time it will take for him to 'get there'. I still love him with all my heart but have separated my love and grief and hurt from my actions regarding him. That's the only way I can handle all this and try to detach in a somewhat healthy way.
((HUGS)) I'm very sorry you are going thru yet another difficult child issue.
