Just stop reading the news for at least a month. Live locally. It'll give you perspective - that these evil men are distant and the effects of their poison only felt indirectly. The news make the effects feel direct, which is part of why you feel so depressed. You feel oppressed, but I am sure that in your local community, you're far from oppressed.
Take a break from the internet and do some work with your hands - go out and do some Christmas decorating, clean the house (or apartment), basically just do stuff that leaves you feeling productive. You'll feel better and more in control.
