You are discovering that when people are driven by greed they will tell any number of lies to shut out people who are, from their POV, ' not to be trusted'. You are a threat to them. She probably hasn't contacted the police. It was just said to scare you away. I worked for a bullying manager who was always telling me that I had upset people. If I asked who they were she would play the confidentiality card. I went to see one manager she said I had upset, in order to apologise and put things right. That nice lady had not been offended at all and, bless her, literally gave me a shoulder to cry on. I swear, you get to the point where you don't know which was is up when you are being bullied. You are being bullied, dear Doormat, and so is your mum, from what you say of their long-standing campaign to control her. She had a right to see you and your daughter. Perhaps your daughter could make some further enquiries while you are recovering from the latest psychological attack. I would recommend that you make friends with the CH manager. She must have seen that all went well on your visit, or other staff can report this back to her. Ideally you want it recorded that mum benefits from seeing you, and wants to see you. Get back to the SW and tell them that you want to go on seeing your mum but have been warned off by your aunt and sister. You may need a more formal contact agreement in place that stops the bullies from barring you from the CH. In the meantime, send your mum a nice card saying it was lovely to see her, see you again soon, lots of love. I am sure this will give her pleasure and it will remind the staff that she has a wider family who care about her.
