NC for this. It's hard to word this sensitively without sounding horrid, but it's coming from a place of concern so I'll try.
A member of my family lives with schizophrenia and has had it for many decades. I don't see her often because she's often non compliant with meds and her unpredictable behaviour when not medicated makes me nervous.
Growing up I have memories of her chasing my mum around the house with a knife and mum having to barricade us in the bedroom and call the police to come and get us out, to give one example. She hasn't been violent in quite a while but is still very erratic.
She remains very close to mum, I would say the pair are co-dependent so to maintain a relationship with mum I do have to have some limited contact with her too. Just phonecalls. I don't make myself available to meet in person as I have small children and am rarely free when not working anyway.
She has been calling me a fair bit over the past two days and I can tell she's not stable at the minute, the 'word salad' ramblings about the royal family is the clear indicator but she has also dropped some concerning comments that she refused to elaborate on.
She's saying things like "if anyone hurts mum I'll smash them over the head, and I won't go to prison for it because of my medical record" said in such a way that implies she thinks that I'm going to hurt mum or wants me to know she's prepared to be violent 
There has been no suggestion that mum is going to be hurt by anybody btw, it's delusions.
She also said "you've been telling mum to kill me, i know you have" but then quickly changed the subject when I asked her to elaborate and refused to go into it. You cannot have a cohesive conversation with her as she jumps from topic to topic and if I were to raise it again she'd deny saying it - but I heard what I heard and it has worried me that she sees me as some sort of threat and will act accordingly.
Whatever's going on in her head this much is true, she sees me and my children as an issue in her life as she doesn't like mum spending time with us - because it takes her away from her.
I'm due to give birth any day now and I'm feeling quite vulnerable, hormones are likely playing a part but I'm quite unnerved and I'm not sure I feel very safe.
She knows where I live and is only 20 minutes up the road, but it's not like I can report what she's said as she hasn't commited a crime, just freaked me out.
WWYD in my situation? I'm considering not seeing mum anymore if this is what happens
