I have found that things can be distracting when you don't really have a strategy for dealing with them and have not taken any action on that strategy. So:

Step 1: Come up with a strategy (a bunch of steps to take to address the problem)...

Step 2: Take action on at least one of the steps. The more steps you take action on, the better you will feel.

Step 3: Vigorous exercise and plenty of sleep.
