Try to catch yourself in middle of a negative thought and turn it to a positive one. This is not easy, but it can help lift you out of a self-numbing sadness, before your mind and emotions spiral you toward a more depressed state. I recently got the opportunity to practice this myself.
Not only does such a mental shift help me to deal with “less than ideal” circumstances, but I think the more positive, gratitude-based attitude and energy I share with my son changes how he thinks about himself and his own health.
My circumstance is just one. This works with issues big or small. You could change any negative thinking to gratitude-based thinking. For instance, say you were looking for a close parking spot on a rainy day and you simply couldn’t find one. You might be inclined to think, “oh, this always happens to me, I can never get a close spot when I need one.” You could change that thought to having gratitude for your car, having gratitude for your legs - which allow you to walk from a far spot. Have gratitude for a warm coat, or an umbrella, or if you don’t have those things, then be grateful for a healthy body that will survive if you get a little wet. Have gratitude for the rain. Step outside your box and expand your perspective. Most of the time, you’ll see that things aren’t as bad as you might think, and that we all have much to be thankful for.
