I've added a new page on strategies for managing anxiety in the links above. My hope is that this can be a helpful reference for you. It's written from the perspective of personal experience.

Mental and physical health are tied together. Reducing stress and anxiety helps promote physical health. Basics of physical health, i.e. good sleep, food, and exercise, are excellent support for managing anxiety.
