I have checked online and usually a lot of it says not to judge, not to speak about experiences, or "truth" because it is useless since their experience are real to them. A little background my grandmother isn't officially diagnosed by a doctor, I've been trying to make sense of the whole situation through the internet and I know that it's not a very reliable source but the symptoms as far as I can see, are there.   


For most of her life, she's been living alone in a foreign country since her divorce with her foreign ex husband. She used to visit us every summer when I was a child but then as we grew older, she stopped coming saying that the plane tickets were far too expensive. Anyway, when we visited her abroad and traveled quite a fair bit, she had already shown some form of paranoia, whether it be others laughing and her assuming it was about her. I thought it was foreigners being racist (I was dealing with quite a lot of culture shock then with this foreigner calling me a rude black hearted evil woman for not signing the uh... petition in his hands.)   


Anyway, on that trip, we decided to get her a smart phone and teach her how to use it so that we could communicate with each other even when we were all the way on the other side of the world. Fast forward to a few months back, she started posting on social media that she feared spy cameras were planted in her TV. (It started with her fear of all these ads on fb showing just at the right time due to algorithms.) She then became convinced everything was being tapped. That she was suffering from extreme deprivation of privacy... eventually, it took a few months to take a turn for the worse - she found suspicious holes being drilled into her apartment, posted about these, just in case. Then, she suddenly posted about burn marks on her hands coming from absolutely nowhere probably lasered all the way from the room a floor above hers. Then, she asked about stigmata, and at this point, reading on it, I was very scared she had gotten involved with a religious cult that did this to her. She also said that when she got back to that apartment, her door had been replaced. She then took her things and for a while went from church to church, and we were all getting very concerned knowing that no one could check on her there as she was living alone. She had assured all of us that she was okay, but never openly talked about these "strange" things happening.  


Then, a few weeks ago, my brother and I being the only ones home, heard the dogs barking madly - and we heard her familiar voice. BUT, she never informed us of her arrival or even that she was coming. Pale as a ghost, she stood in front of us calling out our names with only a small travel bag at hand carrying only the most important documents. A few days before this, I had received a very strange call from her. She asked if we had gotten into a huge family argument, to which I refuted and tried to comfort her that we were really all doing okay. In the end, she came back thinking that my father had died. My brother said she was ready to revise her will...   


She's convinced that someone is doing this to her. That someone was terrorizing her in that apartment where she lived. That her ex husband hired all these people to do that so that she would leave. And she never really spoke of her experience, only saying that terrible things were happening, and I had almost believed her until she said she had become an overnight celebrity where she was living. That ever since she had FB, all these people would cheer whenever she posted something and that all the men wooed when she passed by.  


That night, she stayed in my room and before we went to sleep, she exorcised me and told all these evil spirits to leave us alone because we only wanted to live a normal life. At this point, I really considered that she had joined some kind of cult where she stayed abroad. Then, she asked if it was possible for this thing called 5G or wifi to communicate and directly send thoughts to our heads... then she asked if we could also hear the voices. 

These voices never left her alone. They insulted her, warned her, and frightened her. A few days ago, she almost attacked our household help because of a dream that her hair was being cut. A few times a day, she asks if we're impostors, or sent by someone to monitor her. At this point, as a graduating college student, I could barely hold my sanity - a few times, I had broke down from trying to explain to her that none of those were happening and that no one was trying to hurt her. She stuck by me 24/7 and it was hard not to feel like my whole world was falling apart - so I stopped sharing a room with her and started keeping my distance.   


Several times, I've tried to convince her to visit a doctor but she doesn't believe she needs it. she thinks it's all because she's still adjusting and currently suffering from the lack of sleep from the past few months - 3 months of an average 3 hrs of sleep daily. She said, she doesn't need any kind of pills, that she's healthy. It's just these nightmares, she says, these terrible nightmares.  


I'm not sure what to do. She's pushing us away most of the time, with this creeping suspicion she has for everyone. She zones out when we try to talk to her, and refuses to listen when we explain that it really wasn't us pulling 'pranks' on her. I don't know what I'm doing - if I'm just as much a problem to her as those voices in her head when I try to convince her to take a trip to the doctors.   


Does it ever get better?   
How do I seek help?   
Does she need it, or do I?
