Chronic stress will eventually tiring you if you can't rest. It is best to target stress sources and make changes to relieve stress. This is not possible too often, at least immediately.When the only way out is through, sitting and making a list of things in your life that is important to you. What makes your heart sing? What are you waiting for to do "one day" when you have time? Maybe learning language, cooking, spending time with family, reading, art, playing video games, or sports.
