my grandmother will sometimes get into these moods where she's so hostile. but not in a physically violent way. she literally acts like she's me and my sisters slave. it's so uncomfortable. and when i ask her what's wrong or what's bothering her it's always "oh no there is absolutely nothing wrong. why am i acting like something is wrong? i'm so so sorry i'll just shut up and go away." the only time i ever physically feared for my safety when she was like this was when she was driving with me in the car and she was driving very erratically and i was actually scared we would crash. and when i mentioned it she said "well what i can't even drive correctly now?" and i said i was afraid and she said "oh i'm so sorry how would you like me to drive miss? did you want me to stop for anything? do you want any money for anything? here take my money and we'll stop". but i can't find any definition of this as any kind of emotional abuse. all i know is that when she's like this my sister (14 now) and i (19 now) just lock ourselves away in our room. we don't even try to interact anymore because it's so terrible. she's like that right now which is why i'm asking. i just asked her what's wrong because she was like this yesterday morning but was fine last night and now she's like it again this morning, and she said "well i'm sorry i was fine last night". please someone give me a name or something i can research about what she's doing. I've struggled with depression and suicide for years and i honestly can't take her anymore.
