Crying baby

How do you guys cope with a baby’s constant crying? It seems as though mine never stops crying during the day when I put him down.... if I’m not holding him or nursing him, he’s SCREAMING. I literally am losing my mind and sanity. I’m glued to this baby constantly without a damn break. I stepped away just now to simply brush my teeth and wash my face... came back and he had tears pouring down his face and is covered in sweat. Now that I’m breastfeeding him while I’m typing this, he’s fine 😔
