We are always advised to avoid stress, but it is actually a normal part of our lives. Therefore, instead of avoiding stress, it would be useful to learn how to deal with it. It can cause us significant problems, and it triggers our fight or flight reaction. You have to take action unless you want stress to create health problems or worsen the ones you have already.
Stress is most damaging when it is unexpected, prolonged, and uninterrupted. Still, you can find a way to deal with it by seeking support from your loved ones, as well as with regular exercise. Other methods to manage stress are meditation and other relaxation techniques, as well as structured breaks. It helps if you can learn new coping strategies that would create predictability in your life.
