Hi changeling
I wanted to join Thursday in welcoming you to the site. I know the feeling of crying on the keyboard, I imagine there are many mothers here who have shed some tears for their children. Does your daughter accept the diagnosis she has been given?
Thursday makes a good point about some of the skills or tools taught and shared here, like SET (support, empathy, truth), and wise mind. Are you familiar with these skills? They can make a real difference.
I haven't read Walking on Eggshells, so I'm not familiar with that one. Some members say that The Essential Family Guide to BPD (by the same author) is better because it is includes more current research and is more up to date with common treatments, which might make you feel more hopeful about possible outcomes. There is a review of the book here:
The Essential Family Guide to BPD.
We are here for you. Keep posting - it is very therapeutic, and you will be greeted by so many people with circumstanced similar to your own. You will be amazed. Take care of yourself.
