hotel for a testing center 2 hours away? severe pre-exam anxiety+ dealing with hotel/travel stress (4-5 days out)

My Step 2 is in 4 days (tues), and my current testing center is 2.5hr drive away (midwest) and starts at 8am. I have accommodations and will be testing over 2 days. Honest to god, ive spent a lot of time studying for step2 and i really want to get it over with, but the day before exams, my anxiety shoots up like x10 . the stress of step2 itself + travel/hotel really scares me.

mostly im scared of:

• booking a hotel and then getting panicky/cold feet the night before + unfamiliar environment making me more anxious. i guess the worst case scenario im imagining is me paying a lot of money to book a hotel and then getting anxious last minute and not testing/canceling
• having to book a hotel last minute(and the added stress)
• a closer testing center becoming available after i book the hotel (ive seen nearby dates appear the night before). i havent booked a hotel yet for this reason, but idk when to call it quits on checking prometric when i know ppl cancel last minute

I’m also not a great driver. my family is not supportive and i live by myself.

For people who have had to travel far for Step 2, especially those with significant test anxiety what did you do?

how many days out would you recommend booking the hotel? when should i stop looking for prometric spots opening nearby? would an airbnb be better?

i would appreciate any advice
