Many good ones have already been covered and I highly endorse them. Anything that takes you away from the madness will help. Getting out into nature is good for anyone of us whether we are suffering tRump overload or not.
Here are a few more ideas to try:
1. Do something creative. Paint, draw, craft. Even if you think you dont have a creative bone in your body, you can do art. The craft stores are full of ideas, magazines, materials to get you started. Many offer classes. The very act of doing creative things unleashes a different part of the brain and you will be surprised how relaxing and fun it can be. Tell your inner critic to take the day off and have fun!
2. Read for fun or to inform yourself. If money is an issue, hit a thrift store for books. They are often very cheap and you can always recycle them by donating back to the thrift store when you are finished reading it. Or if it is an especially good book, keep it for your own library or pass it along to a friend or family member.
3. Join a group actively working to get rid of tRump. I know that sounds counter intuitive to what you are trying to do, but hear me out. I, like you, feel such rage at tRump and yelling at the TV is just a temporary release valve. The real rage comes from feeling helpless and hopelessness. If you Channel the anger into something positive and useful, it may change the rage to a force for good.
Hope you find something helpful in the posts I and others have written. We are in deep trouble and many of us are suffering with the anger and worry imposed upon us. We have to stick together, help each other find solutions and above all never give up the fight
