I'll tell you what is making you tired. You see things happening in the world that make you angry or sad, but you can't do anything at all to change them. Adrenaline and other compounds are being released into your body to prepare you for physical action, and you are not taking any physical action. This is making you exhausted. One way to deal with this is to detach yourself emotionally from what you are seeing. Let go of it, and it will no longer have the power to jerk your emotions around. Those juices won't get squirted into your blood and tissues, and you won't get so tired. You can still judge what you see on the intellectual level, but you don't need to engage with it on the emotional level, since it is beyond your ability to change it. On this note, I suggest that you read the *Enchiridion* by the Greek Stoic philosopher Epictetus. It's quite short and you will learn from it.
