The best thing you can do for your daughter is respect her boundaries. If she doesn’t want to talk she deserves that.

If you really do want to make a real change I’d go to a therapist, unwrap your issues, work to understand the full impact your behaviour has had on your children and find a healthy way to move forward. This is for you and the rest of your children (the ones in your care still sound like they would also benefit from therapy and working together with them MIGHT save your current relationships)

I would recommend looking for a way to do some good in this world, such as volunteering. This may do you the world of good mentally, and make you feel less lonely. One day the daughter who doesn’t want to speak to you and the others who have left might recognise the effort you’ve put in and be ready to reconnect.
