That is not to say that we should not expect help, from our neighbors or from the government when it is needed (after all, governments are about more than just collecting taxes and invading other countries, theoretically) or that every element of every situation we find ourselves in is our own fault.
Ayn Rand was wrong, for the most part, but that's a whole bunch of other posts, and I digress.
My point is that frightened or not, it's critical for all of us to believe in ourselves, to have hope and positive expectations that no matter what we are facing, that we have the ability to make a difference, we are not helpless, lost sheep.
If you find yourself having trouble bringing up that positive attitude--reach out. Talk to others, talk to someone you trust.
Then get moving. Do something, anything. That movement, in and of itself, will help you to feel better.
