This is a highly recommended stone especially to alleviate stress, anger/rage and insomnia but I include it in this list because it can intensify psychological issues in some people. It can also feel overwhelming for highly sensitive persons. I choose not to work with it for that reason. Amethyst might be perfectly fine for you but be alert for any adverse reactions.
