Worry, stress and anxiety are common human emotions.  People will find something to worry about even when times are good.

When going through a divorce or other legal proceeding concerning conflicts about children, you will find many things to worry about, and you will have good reason to worry.  But instead of  worrying about your problems, try worrying at your problems.  Instead of letting your mind be consumed with worrying about how bad the situation is, you should concern yourself with what you can do to solve the problems.

Outline your problems in writing.  It helps you to focus clearly.  Then destroy these notes so they are not used against you by the other side.
