My daughter has suddenly rejected me and is being abused
Family counseling needed.
Thanks for using the ask a doctor service.
I have going carefully through your query and understand your concerns. I completely understand the bias your daughter has stepped into. While it may be hard to undo you definitely need to see a psychologist. He can help you take a analytical view of the scenario and to find a way out. You need to convince your daughter that you are a friend and not a foe. This might not be easy but is nevertheless possible. For this you might need to put yourself in her shoes and think. This will help to be more convincing and I am certain that in such a scenario your ex would be unable to misguide her.
I think that this analytical view and counselling will also help you boost your confidence and strengthen relationships. Perhaps your psychologist would be able to meet your daughter as well and give her a different perspective of things.
Feel free to write back.
