how do you deal with toxic family members?

ive been having problems with a few family members. its bad enough if you have issues with your friends, and when situation has surpassed the limit and is beyond repair; the ultimate solution would be breaking up with the friend. correct? but how do you deal with the few bad apples in the family? you cant simply just throw them away. but its also something very toxic to have to put up with their attitude.

what's worse, i think is our eastern culture whereby we cannot say anything against the elders or we're deemed as disrespectful and just simply "kurang hajar". but hello, lady, you've been bullying your family members for decades, and being insensitive towards other people's misfortunes. who is being kurang hajar here? 

i am not an angel, i dont mean to preach. but i hate it when people just simply cross the line and think no one is brave enough to tell them off. i was this close to make my opinions be heard actually. but my "eastern roots" caught the better of me, and ive decided to just keep my distance; and avoid contact. lagi banyak mengata lagi banyak dosa kita dapat kan? so its better if i just keep my distance from you and your FAMILY, and i'd live peacefully with the rest of the family members. 

do not have time to entertain idiots like you.
