There are many crystals on the market that can help with Anxiety such as those listed below. However today we are going to talk about Selenite and how to use it to combat anxiety in general. If you don’t sleep due to anxiety or worrying about what is going to happen the next day, then put some Selenite under your pillow at night. To relax in the evening have a Selenite heart and hold it over your heart chakra, closing your eyes to connect with the stone. When going out keep a small heart in a little keepsake pouch within your handbag or pocket.
