It’s easy to get pushed around psychically by external influences, especially when they’re emotionally “loud”, or your tired, or distracted, or otherwise mentally distressed, and to have them influence your thinking in an automatic and reactive way, and thereby fall into fear and despair, so try to remember to ground yourself in that inner core of your being from which you are able to love (others and the good–truth, beauty, and virtue) and to perceive the ultimate benevolence behind the world.
When I manage to do this, I often become overwhelmed with gratitude for how good my life is, and I’m able to value even some horrific experiences.
