This is a great article by Sandee LaMotte of CNN on how to deal with our current fears. The article states that it has been found that journaling fears and where they are coming from can help process what we are feeling and move beyond those fears. Other recommended tools are meditation and reflective thought. And If the rhetoric that is in the news becomes too much, just turn off the TV or radio. Just tune out!
And this is a wonderful app called Nukemap which helps users see what could happen to their cities but also helps to relieve tension by dropping the bomb on a hostile country. Surprisingly, this calms people!
Pray for peace, it always works!
