Heh, I took a week break from this board as a palate cleanser. Helps a lot.
The trick (for me at least) is be able to disengage from the media while not disengaging from the politics (i.e. continuing to do volunteer work to rally democrats).
They WANT you to disengage completely, that is the 100% the end game. They want and need you on the sidelines watching with apathy and disgust, feeling powerless.
But it's 1000% OK to pull the plug on the media (including this board) from time to time. Don't worry, you won't miss anything, the same basic threat to American democracy will be there, There's really nothing new in the latest Trump tweetstorm vileness that is going to change the fundamental underlying facts on the ground. We all know pretty much where we stand now. Media at this point is entirely optional.
With that being said, activism and volunteer work is not optional, It's your duty as a patriotic American. Many have been called and answered the call to sacrifice much more (i.e. their lives) for causes less important the the fight we are in now (e.g. GWB's Middle East Adventurism). We are fighting to save American democracy, no more, no less.
I don't know about you, but one single truly effective destressor and form of self care for me is to do the work. Volunteer. Control what I can control. Go into this knowing that when called, I actually did something. Not much, not as much as is needed, or as much as "humanly possible", but something dammit. Something more than bitch on a message board, something in the real world.
And, for me at least, it's that taking real world action that is the thing that unclentches the little ball of fear in my belly just a little bit. If you're struggling with anxiety about this election, my advice is unplug the media, and get out in the real world and take action. Action is medicine (in this case).
