I’m also very sorry for your situation. You must feel so alone and lost.
At first sight I thought bad of your mum. I thought “How evil mum” after that I read Yaowen’s reply and helped me to see her in a different perspective.
Keep trying with your daughter, have patience with her, she will realise of the truth.
It’s a very hard situation for you and she must be confused.

I welcome you to the forums. Feel free to expose your struggles, your doubts and people here will listen to you and hopefully they will provide some kind of insight. But, I’m sure we will try to support.
