Hi, I'd like to help you with your question.
It is very important that you contact your local Child Welfare Office to report how your granddaughter is being treated. You can also contact the local community mental health facility and let them know that your granddaughter has a mental health diagnosis and you feel she is being abused.
Also, contact her school counselor and report you feel your granddaughter is being abused. The more people that know of it, the more that can investigate and watch out for your granddaughter.
Let me know if you have any more questions about this.
I hope this has helped,
I haven't heard from you. Did you have more questions or want clarification?
