Im sorry for your situation. I am glad to read that your daughter has a good mother looking after her best interests.
In my case its the mother of the daughter who is a long term addict. Daughter lived with this mother. You can possibly imagine the long term crap she has been put through. I am not the father & I did try to help. Daughters father is also a long term addict.
My point is at least your daughter has a good & caring mother.
I also joined SR in June 2017. Its not pleasant for me to think back to that month & year.
Please take care.
