Resentment is a negative emotional response you feel toward someone or something after you've been treated unfairly or hurt in some way. It often involves lingering anger, bitterness, and a sense of being wronged, and it can persist long after the original incident. Key aspects

• What it feels like: bitterness, anger, disappointment, and a sense of injustice or being undervalued.
• Why it happens: a perceived pattern of being overlooked, betrayed, or taken advantage of; repeated hurts or unmet needs.
• What it affects: attitudes toward the person involved, trust in relationships, and overall emotional well-being.

Common signs

• Dwelling on a past hurt or grievance.
• Frequent irritation or hostility when thoughts about the incident arise.
• Feeling unmotivated to repair or address the issue.
• Believing the other person owes you "justice" or an apology that never comes.

What to do about it

• Acknowledge the feeling: name what happened and how it affected you.
• Assess fairness and boundaries: is the hurt ongoing, or was it a one-time event? Are boundaries being respected now?
• Communicate or seek resolution when possible: express how you were affected and what you need to feel okay again.
• Practice self-care and perspective: engage in activities that reduce rumination and remind yourself of your values.
• Consider professional support: if resentment is persistent or harming relationships, a therapist can help with strategies like cognitive reframing, forgiveness work, or boundary setting.

If you want, I can tailor this to a specific situation (for example, resentment toward a partner, a coworker, or a family member) and offer steps you could take in that context.
