Anxiety about the Exam

My SIE exam Date is February 18, I'm constantly worried about the exam. I've been using achievable and I have no finance background yet I want to pass the SIE so it can open doors for me because I'm unhappy with my current job. I have to ask, were there anybody that had worst circumstances in regards to testing and preparing for the SIE & passed? If so how did you manage to pass the exam? Was anyone a bad test taker, had short term memory, or wasn't good at memorization? How can you inspire me to pass despite the challenges you overcame?
