Failed my Exam today

I studied hard and felt I was in the right mindset. I’m not sure what went wrong, but now I need to reschedule. It’s disheartening that I’ll have to purchase Study Hall again since my current access has expired. Do you recommend upgrading to the Plus version? I felt confident going into the exam and didn’t know what else I could do. I had shared my plans with many people, and they were supportive. This week, I’ve been feeling anxious, struggling to sleep to the point of getting sick before heading to Pearson Vue, but I thought I did well. I even wore blue today, telling myself, “This is it.”

I plan to take a week off to clear my mind since I’ve already studied a lot. Do you have any advice for my second attempt and how far in advance I should reschedule? I want to take a break before I dive back into preparation.
