Every negative word, thought or deed takes peace and positivity out of your account. Cynicism, sarcasm—which some people enjoy and defend—are costly, if your goal is peace.
Biochemically / emotionally (those two are separate in language, but physically they are the same), calmer is healthier. I don't know of any physical condition that is made better by freaking out or crying hard or losing sleep or reciting fears. I know LOTS of things that are made better—entire lives, and lives of grandchildren not yet born—by thoughtful, mindful clarity.
It's okay for mothers to be calm. There are plenty of childless people to flip out. Peek out every few days, from your calm place, and check whether their ranting freak-out is making the world a more peaceful place. If not, be grateful you weren't out there ignoring (or frightening) your children helping them fail to create peace from chaos.
