I have anxiety. It does not have me. That means I am both subject to anxiety and am able to control it. Sometimes that control comes in the form of breathing exercises, movement, or stillness. Other times it happens through mental processing or talking it out in therapy. Daily it means taking my prescribed medication, including those that aren’t just for my anxiety. Keeping on top of my allergies helps me feel more awake throughout the day and less likely to want to nap.
Whatever form your control takes, I encourage you to figure out how and why it works for you so that you can continue to use it in a healthy manner.
