Frustration is anger with the volume turned down. Whether we feel frustration, grief, anger, or sadness, all these emotions are reactions to situations not being as we want them to be. No matter how justified, emotional reactions are hard on us.
I have been trained to see emotional reactions as red flags, informing me that I need to make a change. Sometimes an attitude change, sometimes an action is needed, and sometimes both.
When we see emotional reactions as a wake-up call, we are less likely to repress them and we can learn to respond in proactive, creative ways, before these self-harming emotions take root.
