Hi there, I completely understand where you are coming from. I have also struggled with anxiety related to fears and phobias. Crystals have proved to be hugely beneficial in my healing journey in managing my anxiety and promoting courage.
When it comes to my fear of heights, I found that using fluorite has helped me tune out the anxiety and focus on a more clear state of mind. It enabled me to see things more calmly and helped me stay connected to the present moment. I also carried citrine with me to promote confidence and courage.
When it comes to spiders, I found that labradorite has helped me let go of some of the anxiety that comes with thinking about spiders. It's a beautiful crystal that promotes transformation and promotes inner power. Black obsidian also helped me ground myself and provided me with a sense of protection.
Lastly, for my fear of public places, I found that using blue lace agate helped me relax and stay calm in social situations. It's a beautiful blue crystal that also promotes communication and helped me feel more at ease during social interactions. For courage and confidence, I used carnelian which is an excellent crystal when it comes to promoting courage and confidence.
Remember to be patient with yourself and to find what works best for you. Every individual is unique in their experiences and in their process of healing. I hope that helps you as you embark on your healing journey.
