When you attack somebody, get all revenge-y, blame somebody else for your bad stuff, obsess about the wrong somebody has done you……you give them all the power.
Don’t do that!
Feel your feels, get angry, whatever, but keep it short and keep your energy with you and focus on your life, your dreams, your growth, your wellbeing.
Do not direct your precious inner power towards people and things which undermine your splendour. Keep that power.
