NCLEX question

I graduated earlier this month, I am a GPN scheduled to take her NCLEX in early January, I am freaking out bad. Everyone that took it in my class so far has passed with 85, my friend took the whole 150 and got her results today and passed. I also know someone who shut off at 95 questions and failed twice. My question is what if I shut off at 95 or 100 questions? Does that mean I fail? I am so scared. I am having anxiety really really bad over this. I’ve been studying every night. I do ATI and UWORLD and get in the percentile that they are asking for. My probability of passing proctored exam I got a 99% but I am just terrified. What if I take the test and it’s a bunch of stuff I don’t know. Am I over reacting? I am so scared. I need advice bad.
