Hi I have a very similar story to yours I just posted for the first time today. I can only offer you hope and understanding from one mum grandma to another as our daughter is in very similar situation but she has finally seeking help and hope for the best outcome as possible. It's a long hard trek and our girl is 34 now and two adorable grandchildren all I can say you are allowed to have those feelings of frustration hurt and anger but don't give up hope, it's hard they test you! But deep down there is that beautiful soul you bought into this world and I hope she returns to you. I still live in hope and it's the first time in years that it may happen this time. Good luck stay strong and take time out for you.
