Yep. Each time you perform the same action, say the same words, think the same thoughts the connection of the neural pathways responsible for those things are strengthened. It is why depression and anxiety and other mental issues are so hard to reverse. It is possible though. I urge anyone who thinks they have depression to look up a book called “The Upward Spiral.” It is co-written by a neuroscientist and a psychologist and was really eye opening for me on the inner workings of the brain when it comes to depression and anxiety and has helped me at least start on a path to making myself better.
