Try to look at the positives. I know how hard it is to watch our kids suffer...at the same time...try to remember the qualities she is gaining from this experience...Not that we WISH it for our kids...but, kids who grow up in situations like ours tend to be more compassionate, resilient, know their own strength, have more insight into themselves/others/relationships, more able to identify feelings...
This could be THE OPPORTUNITY for her to learn how to ask for what she needs in life. And, that, in itself, is a HUGE life skill. Asking for what you NEED to get through a difficult time.
In the grief book I'm reading...she talks about the importance of rising above the situation. In other words, the people who use the abandonment to sort of propel them upwards are the ones who come out ok. Doing the things outside of our comfort zone are the things that will give us the confidence we need to overcome the rejection. Sorta show yourself that you really can do things you never thought you could...I think this could be a great opportunity for your daughter to learn that she REALLY CAN handle this huge change.
Tell her, "You CAN handle this!"
