Wow, what tough news. I remember your daughter’s struggles (and the anguish that they caused you). She is older now and many times that can help. At this point I think you are on the right track just offering support since she isn’t asking for advice.
I really do think a visit with NAMI like @MaineLonghorn suggests, might help you define your daughter’s strengths and weaknesses and how to del with them.
Sending all positive energy your way. So many of us could be in your shoes.
