I have a personal connection to a couple of people in the Middle East and someone who lost their life at the hands of ISIS/ISIL. Their last email haunts me. I have been alarmed by them and by Ebola and all the other crazy stuff happening in the world.
I don't watch the news or any info about it anymore - or any news. I used to. It just made my PTSD worse and paralyzed me to respond to it well. I get tempted to go back and watch. When it comes times to vote, I will become more informed again - but only by reading it. Reading it tends to take out some of the fear and emotion. I will do it with friends too. Not alone. It's scarier to face alone.
I also take reasonable measures to stay safe in public - stuff I would do anyhow.
I don't want to get all weirdly religious, but I asked my therapist about it - and one time, she said, "well, what do you do with death?" She is not of any particular faith but is supportive of mine. Her questions deeply challenged me and brought me back to matters of faith. I am coming to an increasing place of peace about what is going on with ISIS/ISIL. Really, the only thing that calms me is knowing I am not alone and connecting to my faith, my God, and my friends (online and offline). It's a tough thing actually, as the bible talks of a time that will come where the proverbial stuff will hit the fan. So I kind of wonder at times as I connect to God if that time is coming. Which makes me feel scared. But here's the thing about my faith, I have a God who was stressed to face death too - a God who understands me even if I don't understand God. And, it turns out ok in the end. There is so much reason for hope in this dark world. I have a hard time holding on to it, but it is there.
Disconnecting from the news and connecting faith and to others has made a big difference for me.
