Hey @Betty-Jane26
It sounds like you've been an incredible source of stability for your nephew during a really frightening time. That safety you provided in February likely made a world of difference for him 💚
It's understandable that you're feeling unsure about the next steps. Balancing the desire to keep a loved one off the streets with the reality of managing untreated psychosis is an immense weight to carry, even with your background in nursing.
Since your nephew is fearful of being "locked up," he is likely operating from a place of high anxiety and hypervigilance. Sometimes, instead of trying to convince someone their reality isn't real (which can increase resistance), it helps to validate the emotion behind it. You could say something like "I can see you're really worried about losing your freedom, and I want you to feel safe here." It might also be helpful to have a "low-pressure" conversation about what staying with you long-term looks like. This isn't about an ultimatum, but about exploring what "staying safe" means for both of you.
Since he is resistant to formal treatment, you might want to look into community-based options that feel less clinical or restrictive. Mobile outreach mental health teams may be in your area. They can visit your home for a chat and support, rather than having to visit a hospital. Step-up/Step-down services might be an option, these are residential, community-managed environments that feel more like a home than a ward. I also suggest looking into peer-led support. Sometimes talking to someone who has "been there" and experienced psychosis can bridge the gap in a way family and clinicians can't.
You aren't alone in this 💚
Does your nephew have any particular hobbies or interests that usually help him feel grounded? Sometimes focusing on those small "anchor points" can help stabilise things while you figure out the bigger picture.
