This reminds me of Jerry Stiller... I think I would say it like he does.
My blood pressure could go higher and I would still live.
When you are in a situation you cannot do anything concrete to change, holding it lightly (in the sense of not letting it consume you and screwing up your life or health) is not a wrong.
I tend towards anxiety, so this was a technique I learned to cope with things I can't do anything about.
Prayer is good. I have seen more than one thing that I would put in the miraculous or nearly so category come about through that.
Personally, I am not praying for peace. I am praying that God watch over Israel and that his will be done. I have to put it in his hands, because my hands are pretty much powerless to affect what's happening there.
And I refuse to let the stupid news services ruin my life - especially when you know they aren't really telling you what's going on as much as they're telling you what they want you to think about what they want you to know is going on.
