She is not diagnosed but often tells me of seeing people in and around house.She also asks me to look don't I see them. Or that she was tired of them she going to take the lock off door and get them out or ask me to make them leave. Once she ask me if I was going to just walk by my father who is deceased and not speak. How do I respond . Im trying to get her help but my sister and nephew are interfering saying she is okay and just stresss.
