Do you think people who threaten to kill themselves are attention seekers?

I have a toxic and evil grandma who’s constantly victimizing herself is extremely manipulative and often provokes arguments mostly with my father her son. She always ends up crying so everyone feels sorry for her and then she threatens to kill herself. She never attempted to do anything like that she’s 84 years old and cam barely move I think she just wants some attention when she says these type of things. What’s the best way to deal with this situation?
