She will never learn
I don't want to sound mean but NO SHE WILL NEVER LEARN as long as 'mommy' is there to 'catch her', fix her wounds, etc.
You know it was absolutely AMAZING, but after my folks cut off ALL contact with me, hanging up the phone if I called and closing the door in my face if I came to the house, how easy it was for me to figure out how to get to the hospital when I would realize that I had done damage to myself.
I know you love her, but, continue to love her this way and you may love her right into the grave.
These are HER RESPONSIBILITY. Her actions are bringing on these problems, whether it's a burnt thumb, a bad gash in her leg close to an artery (like I had) a split forehead (like I had), whatever. The longer you continue to step in, the longer it will take her to realize FULLY where her actions and drug usage is taking her.
Please try Alanon and/or Naranon on a REGULAR basis and continue to post here, and let us know how you are doing, as we do care very much.
Love and hugs,
