Your exact question is unclear so I will provide a broad answer. I am sorry that this is happening to you and your family. Certainly, this has to be challenging for everyone involved.
It’s difficult to know what might be wrong with your mother. It could be that she’s experiencing severe psychological distress and/or a psychological condition. She seems unwell. Going to live with your grandparents was a very wise idea. You should stay with them as long as you can or need to do so. Hopefully, your siblings are living there too or found a stable and safe place to live.
In the meantime, encourage your mother to seek help. She may take your advice but be prepared for the fact that she may not. If she is psychologically unwell, she might not be able to recognize her symptoms as being problematic or appreciate how her behavior is affecting the family.
You should also partner with your grandparents and siblings to encourage your mother to seek help. Consider it a family intervention. If you were all to take a unified stance, it might help her to realize that she needs help. You might also try family therapy. She may not be willing to go to one-on-one counseling but she might be willing to try family therapy. If everyone is willing to go, she might be willing too. I hope this helps you. Don’t hesitate to write again, if you have additional questions. Please take care.
