Anxiety

I'm scheduled to take boards tomorrow morning and I'm so incredibly anxious. I have been studying for 6-8 hours a day on off days and 2-3 hours on my work days. I've been a nurse for three years and two of them spent as an intermediate nurse. I feel like I know my stuff and then anxiety gets the best of me.. I didn't use Barkley or Fitzgerald as I couldn't afford it but Mometrix and basically my textbooks. If anyone has any tips please let me know 🥹
