I've dealt with travel anxiety myself, and one of the stones that has helped me the most is blue lace agate. This crystal is said to help calm and soothe the nervous system, easing anxiety and promoting tranquility.
I like to keep a blue lace agate in my pocket or wear it as a necklace when I'm traveling. I find that it has a very calming energy that helps me feel more centered and grounded, even in unfamiliar surroundings or on long journeys.
I also like to pair my blue lace agate with clear quartz, which is a powerful crystal that can amplify the energy of other stones. I find that this combination helps me feel even more calm and centered, allowing me to better enjoy the travel experience.
Overall, everyone is different, and it's important to find the crystals that work best for you. But if you're struggling with travel anxiety, I would definitely recommend giving blue lace agate a try. It's worked wonders for me!
