Crisis management is an oxymoron. You can't manage a crisis; you can only manage response to it. And sometimes not even that.
There is no perfect way to respond to a crisis. You can go into action mode as focused and efficient as a M*A*S*H unit with incoming wounded. You can close your eyes, hold your breath and jump off the Titanic.
The major thing is seems nowadays is to respond differently than your usual way of doing so. If you're used to being super competent, maybe it's time to break down and cry. If you're used to running for the hills, maybe it's time to draw out your saber and charge. If you usually tough it out alone, it's time to ask for help.
If you've had a series of mini-crises prior to the current one, then this could be 'final exams' time when you put what you've learned into action.
It's important not to resist a crisis, it only immobilizes you. Nor can you avoid it, or it intensifies. However don't make something a crisis that isn't, or take on someone else's. False crises are a waste of energy and provide no real growth.
You can try relaxing into the crisis. You can reframe it (what a great Hollywood movie/TV series it is)!
And remember that crises don't last forever (they just feel that way).
Try this for a week with whatever crisis (big or small) and see what happens!
