Many of us believe that we are our thoughts, or rather many of us don’t stop to think whether what our minds are telling us in the form of thoughts is true or not, because the belief that thoughts are us is so ingrained in us. And so many of us ruminate, get stuck in the cycle of repetitive thoughts, usually negative, going on a mental merry-go-round, repeating the same thoughts and feeling the same (negative) feelings, like a broken record.
By letting the problem replay over and over in your mind, you are engaging in a process which is called “rumination.” Rumination refers to the tendency to repetitively think about the causes, situational factors, and consequences of one’s negative emotional experience (Nolen-Hoeksema, 1991).

What is worse is that neuroscience tells us that the more we do it, the more we reinforce related neural pathways, or in other words the deeper the groove of our mental record, the worse off mentally we are and ruminating (and descending into resulting emotional darkness) becomes something we engage in regularly and automatically. It can even evolve into a mental health illness:
Rumination is sometimes referred to as a “silent” mental health problem because its impact is often underestimated. But it plays a big part in anything from obsessive compulsive disorder (OCD) to eating disorders. Rumination: The danger of dwelling – BBC News – BBC.comwww.bbc.com › news › magazine-24444431
In the first couple of weeks of The Great Lockdown, I have spent too much time on the news feeds obsessively reading the news and feeding my fears of uncertainty and missing out. Once the panic subsided, I have cut the news intake to preserve my sanity. I now try to check the news no more than once a day and sometimes forget to do so. I started collecting positive news in the midst of the pandemic. Here are some that caught my attention. Add links in the comment if you have others to share. Stay safe and stay sane, fellow nomads!
