I learned a trick to help with pre-surgery anxiety before my second of three surgeries. My surgeon recommended listening to calming music around the same time as check in for a couple of weeks before the surgery. Some places will even allow you to take the music in and listen to it during surgery!

This really helped me to relax and maybe it would be worth a try for you. I chose nature music but they also recommended classical. I also listened to it during recovery when things in the hospital got overwhelming. I could put on my headphones and close my eyes and just refocus a bit.

Best of wishes with the end results.
