Nclex Confidence In The Toilet

I am preparing for the NCLEX-PN after being officially graduated 1 week. I have been working with the Saunders Comprehensive Review and the new question and answer format. My 2 big problems are: (1) I AM WEAK IN PHARMACOLOGY PERIOD and I feel like an idiot when I do the review quizzes because I never get more than 7 out of 10, and most of those I just guess and yes, I read and try and understand the rationale for the answer. I just plain don't know my medications literally EXCEPT LASIX and I don't know what to do (2) When I do questions in other content areas I range between 7-8 questions correct.

When I was in school, I NEVER HAD THIS MUCH TROUBLE. I know that I know the material minus the meds but my confidence is in the toilet. I don't know if I can realistically study for this FINAL EXAM. I have said that I was going to schedule my test date as soon as I got my ATT just to get it over with because I feel like the worse I do with the practice questions the higher my anxiety gets and makes me believe that Im either not ready or Im so nervous I cant answer the questions which in turn makes me feel like if I cant answer a sufficient amount of the questions to the satisfaction of the disk, then I feel like when the REAL TIME comes, Ill be the same way, spending all 5 hours at the testing center and failing. I know one thing for certain, if I fail, I dont have the money to take it again. THIS LITERALLY BRINGS ME TO TEARS REGULARLY CAUSE I DONT KNOW WHAT TO DO. SOMEBODY PLEASE HELP GUIDE ME IN THE RIGHT DIRECTION.

PS

This anxiety I am having (and will continue to have until I take this test) is not a joke and not meant for attention, it is meant for help.
