I agree with Pfrog wholeheartedly ~ I don't think that I could put it any better!
Just wanted you to know that I understand. I've been there too & I also have to avoid news, dramas, talk radio, etc. as well. It's much too stressful for me to handle. It's not worth the horrible nightmares either.
I've also had to step back from my family to gain a better sense of sanity. I last saw my mom about a month ago ~ while I was in the hospital, watching my brain activity. The night that she left until about a week later, I kept waking up to horrible nightmares as I was shouting and making striking movements, to protect myself. Family just is not worth that high stress and chaos in life.
Wish you the very best!
