Hi Witzend,
something you said really resonated with me--"your daughter never will be able to move on from this if you don't." How I wish someone had said that to me several years ago!
I found that I felt so guilty for my perceived contribution to both my daughters' problems that it kept us all mired in the mud. I had to quit blaming myself and move on--I was not able to be a good or effective parent til I did that and both my dtrs needed a parent who was strong and confident in order to move on.
Your whole post was awesome, thank you!
Jane
