Please pray for me - I'm taking NCLEX PN next week...

i graduated at the end of march and will take my pn nclex next week. i haven't been feeling very confident bc i felt like i didn't retain any knowledge in school. it was kept in my short term memory for a test and forgot the next day. our school has been using kaplan and have barely passed the quarterly test. i did the online review sessions and they worked great. i've been on the website practicing questions but get discouraged easily. since april, i've been meeting with groups almost every week, doing 30-50 questions. i also took the kaplan review class online for 2 days back in april.

these last 2 weeks, i've been studying with 2 people and we go over kaplan questions 2x/wk...about 50. also, i've been praying and saying affirmations that i am going to pass. i've just been going through the allnurses studyguide and just reviewing content but someone advised to just keep doing kaplan questions and read the rationales... please pray for me... i feel so bipolar right now :(advice? i also haven't been able to sleep the past 4 nights. i sit in my bed and hope to sleep...drank some chamomille tea.... work out here and there...no caffeine past 6 but i'm still sleeping 4 in the morning...aurgh! at this point, i'm just tired of doing questions... i can't explain it... i don't know if what i'm reading will even stick in my head, at this point... help
