There's a difference between spending all your time worrying about what might happen, and being concerned for what might happen.
I am concerned, but what's the point of me sitting at home and getting into a state about it? But that doesn't mean I don't give a shit about those who have been affected or might be affected in the future. It seems that you can't say you're not worried without being accused of being selfish and heartless.
My family and I are being sensible, taking the recommended precautions, reading up on the facts and not listening to the scaremongering.
