Recent interactions have taken people by surprise because your irritability and aggression are out of character.
Your reactions have been amplified due to emotions that are waiting to be acknowledged, assimilated, and released. The good news is your pent-up frustration comes from surface issues that can be easily resolved with communication.
Consider what or who has been troubling you. Are there things left unsaid? Has someone said something that has offended you, or have their actions been unjust? Don’t avoid it or waste energy mentally replaying the situation. Have a conversation to express how their actions triggered your feelings, to tidy up loose ends and resolve any outstanding issues before they compound.
