Help? Really need some advise :(

I failed NCLEX twice, both reached 265 and the requirements expire in November or December so I need to take it. But its so hard to stay focused and study with all this ******** going on, my mom constantly nags me and puts me down for failing, she yells at me like "You failed cause you don't know the answer!", "even if you take a third time you'll fail!", "you keep reading but you still can't get it!" and a whole bunch of other narrow minded ignorant responses. It's so frustrating cause I know I can but she keeps pushing that I'm dumb and she has zero knowledge about NCLEX. Then my aunt who's a nurse keeps saying "you don't need to reach 200, just answer correct and it will shut off" well yeah if I'm consistent. WTH!! It's like nobody understands me, I want to move out just to review but I'm broke and jobless right now. I should just be able to shut this kinda stuff out but I can't especially since I'm stuck living with my mom. What do you suggest I do? It's a confidence killer and I can't stay focused cause I want to kill somebody! I'm so angry all the ******* time. Please help me I'm so lost and no I can't talk to either; I've tried but they're old and narrow minded and think they're always right. This has been my problem since my first AND second take.
