If you are afraid right now, I have a suggestion.
Make a plan.
Plan on what you are going to do if things don't go the way you want them to. Turn off the TV for a bit and start working on how you are going to move forward.

Why?

Because if you have a plan, you will start to feel like you have it covered no matter how things go. You will feel prepared.

Not only that, you will get out of the manufactured panic for a minute. People are making money off of your fear right now.
