When caught in a depressed mood, it's tempting to feel that life is too hard, that you can't go on. It's this type of thinking that winds up feeding and sustaining the mood. Consider trying this: do nothing!
All too often we go to battle with our negative, spiraling thoughts. We beat ourselves up, which only adds fuel to the dark mood. Instead, next time you're in a slump of negativity, don't engage in debate, guilt, or self recrimination--in essence, don't resist, simply yield. Just allow yourself to ride out the mood with the understanding and conviction that, 'this too shall pass.'
The key is not to get caught up in a dance with your depressed thoughts. The more you ruminate, worry, or antagonize yourself, the more you feed the mood instead of starving it. By letting it go, turning away, distracting yourself and not engaging a mood with persistent doubts, fears, or negatives, the more you allow yourself to reduce psychological friction while ensuring that you're not a victim of your mood.
