She was sectioned during a crisis and is now under Section 3 voluntarily. She's been prone to meltdowns over the last couple of years but has been helped with antidepressants and counselling. She phones me occasionally and most of the time she's rational and logical, she likes the unit and praises the staff. She knows she needs help. However, she is convinced her father is in the unit, I know this isn't true. Their relationship isn't good, he is elderly, in poor health and lives in another country, she is low contact. His "presence" there is distressing her. I haven't contradicted her, I mostly just listen and reassure her that she's in the right place, that I will always be her friend and that I'm proud of her for seeking help.
Is this the right strategy? She also thinks people are spying on her, but it's the delusion about her father that is most worrying.
