Is OTHER wrong in the post ? POST : First time posting, just started reading some of the posts here, and seeing as ya'll have solid judgement, I'll tell my story.

For ease of reading my mother is M, grandmother is GM, Grandfather is GF, and father is D.

GM was raised in Mexico and is extremely racist, to the degree that when M was younger GM would berate M for being slightly darker than her cousins and classmates.  M has [Meniere's disease](https://www.healthyhearing.com/help/tinnitus/menieres-disease) and now whenever she gets overworked or really tired she ends up bedridden for about full day.

Thats just background info the meat and potatoes start about 2 months ago when GF first went to the hospital. She decided around that time to leave for Mexico, cause "If he dies there I can't be in that house alone" she spends her time there partying, and discovers facebook where now she is compelled to put out every single thought and feeling she has. When she comes back GF is still bouncing in and out of the hospital and everyone is preparing for the end. While GM lives near M she starts demanding M do things like take her shopping, read her mail, get her groceries, and basically take care of everything pertaining to GFs death. After so many years being married to D now GM starts getting on M case about the decision to marry D and move to America, M being WAY too nice for her own good does everything GM asks. Emotional stress and overworking finally hits M like a truck and she ends up bedridden a full week, after a few days D takes M's phone and iPad, because GM was constantly calling, messaging, and face-timing demanding stuff or complaining that she isn't getting any help. My sister has been sent over a few times to take care of M. Now it's just this past week, I've got a provisional license so I can drive with an adult that has their license, now I've been tasked with driving her around, all while she tells me to be grateful she took care of herself and she is still alive, and that if GF had been a better person he'd still be alive. I'm a high schooler taking a few college classes and I'm having a hard time keeping up whilst constantly taking care of GM but I'd rather do it than M who is also in college. GM also frequently tells me and my sister that we need to either marry white people or white looking Mexicans, and that we should never be in a relationship with another black person or any asian people. GM now has taking to badmouthing my new aunt that my uncle married while my grandfather was around. GM threatens to move to Texas with her gall pals if she isn't taken care of and almost daily mentions that we should all be grateful she is alive.

TL;DR AITA for hating my racist, rude, and fairly annoying GM
