How do I stop feeling drained from angry customer calls all day?

Call after call, you take someone's anger and hand back a smile you do not feel. By the end of the day there is nothing left of you. That hollow feeling is not weakness. Faking cheer while swallowing hostility for eight hours is genuine labor, and it has a cost no one warned you about. Here is a truth to hold onto: their anger is almost never about you. You are the voice they reached, not the cause of their problem. When someone unloads, it can help to picture it passing by you rather than into you. You can be kind and helpful without agreeing to absorb every ugly word as if it were true about you. Then refill, even a little, between and after calls. Ten seconds of a slow breath before you pick up. A real break where you are not bracing for the next voice. Something after work that is entirely yours. You are pouring out cheer all day. You have to put something back in, on purpose, or the well runs dry. Guard your own supply like it matters, because it does.
