How can a person keep from feeling overwhelmed by all of the negativity that surrounds us today?

We are constantly bombarded by negative news about our out-of-touch & unfeeling government, news about the damage we are inflicting on our environment, news concerning the intolerance represented by all religions, news about looming shortages of food & fuel, news about the dire straights of a too large percentage of the people in the world, news about the decline in education levels, news concerning the increasing negative attitudes towards women (& those whose gender does not fit into the neat boxes society imposes), news about the continuing wars in which the US is fighting, etc. Realistically, how does the ordinary person deal with this inundation of situations over which we have no personal control? We can see all of the problems, but unless you have some level of personal wealth, you can do very little about ANY of these problems. So, how does one cope with the ocean of negative news? Ignoring it will not make the actual situations go away & ignoring it will not prevent the actual situations from having an impact on you – so how does one keep from crawling inside of themselves in frustration & desperation?
