Do you have an anxiety problem? Do you feel like you are in control of all the situations around you? When something goes wrong, even if it is not your fault do you feel like if you have done more you could have stopped it?
Allow yourself a set amount of time once a day to worry about all your problems.
Once that time limit is up you are not allowed to worry for the remainder of the day.
Reassure yourself after your time is up that you have done all you can to solve your personal problems and you are the only person that you can control. You are not responsible for every outcome or every decision someone else makes. You cannot be held responsible for the actions of others. Then release all worry or attachment to issues that do not involve you directly.
