Hello Wispatea,
I’m so sorry to read that you are going through this, it can be incredibly difficult and disheartening when children begin to mirror behaviour that they have witnessed from an abusive parent.
It’s great that you feel able to reach out for support with this and that those professional services are already aware.
You might also want to connect with Family Lives, who are a parenting and family support service. Their website is https://www.familylives.org.uk/. They have a webchat, helpline and email support service.
Take care and keep posting,
Lisa
