Bring awareness and let it go.
It is not difficult at all to take charge of your health and happiness. You have been created with all the tools within and around you to keep you healthy. You just don’t know how to use them and instead, by creating stress and anxiety you are running from one place to the other without knowing where you are going. It is a never ending process. Your body keeps on telling you if it is in stress or if it is at ease. You are running when you feel stressed and you are running even when at ease. Running is not the solution to your problems. You need to sit down and learn these tools and how to use them and live with any fear.
You just need to bring awareness.
