My mom is crazy? I don't know what to do?

ok, my mom is crazy...literally. i've lived my life with my mom and have learned to deal with her delusions (government is bugging our car, someone could read her mind, the neighbors were stealing her stuff, there was the possibility that she is the child of marilyn monroe and jfk, she used to go to high school with brad pitt *i checked...no* etc.) and since a child, her hatred for my dad...like outright telling me that my dad is a cheapskate who has hidden accounts of money and constantly tells me she hates him and wishes she'd never married him since i was 5 (i never thought so thank god)

i always listened to her stories about her childhood that were brutal (being kidnapped but escaped by using shoelaces to strangle the driver, her sister had a baby with their brother *related*, a girl she knew got killed on Halloween by a crazy guy with an axe, her brother got their house shot up because he didn't pay for his drugs, her mom stabbed the top of her sister's mouth on purpose, she used to be engaged to a bunch of rich Arab guys, her dad used to beat up her white boyfriends (grandpa was Lebanese and the family is Muslim) etc.) and i always believed it

then my siblings started to tell me "you know she's lying right?" and i was just O.O

turns out my siblings HATE my mom and i'm the only one left who likes her...

here's my problem:

it's gotten hard to hang out with my mom...i'm scared to start hating her like my siblings and that will just make her sadder since her last child will ignore her like the others

i've gotten a short fuse around my mom~if she starts to even go NEAR the topic of my dad (who i love dearly) i basically yell 'shut up' compared to my usual 'please stop'...same for the crazy ideas

should i just try to be patient with my mom or what? it's gotten exhausting and i'm afraid i'll start hating her...

p.s. sadly, i'm not trolling :(
