That reading or participating in to many negative conversations can affect you negatively, and in time make you pessimistic about life and also affect your health.
It’s not to say that one shouldn’t oppose or seek information or seek to inform others but that it should always be kept in balance.
If you see you are being affected, take what I call a garbage break and avoid all pessimism until you feel renewed. Like right now. I need a garbage break. No politics, and no news for a while. Just me, and my garden and my dog and some fall cleaning. Going to hit my closets hard and find stuff to give to charity. At least the last one is my plan. Hopefully most of my clothes don’t convince me to give them another year. LOL
