There is an upside to large-transformative-earth-shaking-life-changing change. It creates new thoughts, ideas and patterns.
Having the world turn upside down gives you two basic choices - you can hide under the covers or you can use the moment to try new things. It's a moment when you have the ability to lead or leave :-)
By leader, I don't necessarily mean someone-in-charge-of-the-whole thing. "Leader" is someone who, at any point and any level, helps others manage the upheaval.
This could be anyone of us if we view leadership as: identifying blocks; offering bridges; encouraging collaboration; seeing links; creating a vision; and delegating the solution details.
My mentors challenge me to be an "agent of change". I accept that challenge and pass it down the line. Consider: When the world turns upside down, it's an opportunity to influence the outcome for when it goes right side up.
