Well, the first thing required is to keep our heads screwed on and maintain our sanity, for it's easy to get so concerned that we can't even think. There is no one way that is the best, but look for something that you enjoy in your life, something that is also productive and keeps you thinking clearly, and then you can deal with those sordid things around you, especially if you maintain the strength of your faith in God. There are no situations or problems in this world that He can't help you with and solve, but if we instead allow our minds to be so cluttered with the nonsense that surrounds us, we'll never get anywhere. So, take it to God and ask Him for help through prayer and it is doable. Then take a break from it all and focus on something in your life that truly makes you happy and the storm can be dealt with.
No one else can tell you what does that for you, but for me, it's writing. When I write, I can escape all my troubles and just let my mind freely wander and take me where I want to goe, if only for a little while. And I'm not necessarily talking about writing books, but even such things as a free-wheeling blog like this one. I can think about an issue or a joy in my life and then just put it down on paper. The process of writing it down just brings it all out in the open and then, when it is there to read, my head is clear. Sometimes I read it and throw it away, other times I share it with others like I am doing here but, either way it does free the soul and sometimes it is of value to others as well. And I find that when it is done in conjunction with turning those things over to God in the process, I am freed up to clearly focus. When we are successful in focusing on things with God guiding us, it is truly amazing what we can accomplish amazing while also being at peace.
So, yes, pay attention to all those things going on that seem just not right, but work on the ones you can do something about and clear the rest out of your head. And whether it's reading, writing, a hobby or even a bit of exercise taking a walk or a jog down a beautiful country lane enjoying nature, do something to get the nonsense of a chaotic society and body politic out of your head, at least for a while. You'll feel better, life will look better, others will appreciate you more and enjoy your company and tomorrow will be a brighter day, a day when you can do something positive to make things better as well. Try it. After all, what have you got to lose?
