Anger is often described as a secondary emotion. This means that while it’s the feeling we notice most, it often acts as a shield for deeper, more vulnerable emotions like hurt, sadness or fear. When someone experiences a situation that feels unfair or disrespectful, anger is a natural response. However, when that anger lingers long after the event has passed, it can turn into resentment, a heavy, persistent feeling of ill will toward a person or a situation.

Holding onto these feelings can be physically and mentally draining. It may feel like you’re carrying a heavy weight that prevents you from being fully present in your life. Learning how to let go of anger and resentment is not about pretending you aren’t upset. In fact, suppression, the act of pushing feelings down, often makes these emotions harder to process and may contribute to ongoing distress. The goal is to process the emotion so it can move through you, rather than staying stuck.

1. Practice radical acceptance and validation.

The first step in letting go is giving yourself permission to feel your emotions. Many people try to logic themselves out of anger, telling themselves they shouldn’t be upset. However, your emotions are a signal that a boundary was crossed. Acknowledging your anger can be an important first step in understanding and managing it.

Radical acceptance doesn’t mean you like what happened. It simply means you accept the reality of the situation without trying to fight it.

• Label the underlying feeling — Look under the anger. Are you actually feeling lonely, ignored or betrayed?
• Acknowledge the impact — Admit that the situation was difficult and your reaction makes sense.
• Release the shoulds — Let go of thoughts like this shouldn’t have happened. Accepting that it did happen allows you to move forward.

2. Use physical movement to release energy.

Anger triggers the body’s fight-or-flight response. Anger can activate the body’s stress response, leading to muscle tension and a surge of adrenaline. If you don’t give that energy a place to go, it can stay stored in your body as resentment.

Engaging in physical activity is associated with lower emotional intensity.

• Vigorous movement — Activities like running, dancing or lifting weights can help burn off the extra adrenaline associated with anger.
• Gentle stretching — Anger often settles in the jaw, neck and shoulders. Stretching signals to your brain that the threat has passed.
• Breathwork — Using deep, slow exhales can help calm the nervous system and lower the physical volume of your anger.

3. Shift from rumination to perspective-taking.

When we feel resentful, we often get stuck in rumination. This involves replaying the hurtful event over and over in our minds. While it feels like you’re searching for a solution, rumination often just keeps the anger fresh. Perspective-taking is a tool used in therapy to help break this cycle.

This isn’t about making excuses for others. It’s about broadening your view so the event occupies less space in your mind.

• Look at the whole picture — Consider the stressors or circumstances the other person may have been facing without excusing their actions.
• Think about your future self — Ask yourself, “How much will this matter to me in one year?” This can help put current resentment into a larger context.
• Identify your agency — Focus on the parts of the situation you can control, such as your own boundaries and reactions.

4. Write a release letter.

Processing resentment often requires expressing words that were never said. However, talking directly to the person involved isn’t always safe or helpful. A release letter is a therapeutic exercise that allows you to get your feelings out without the need for a confrontation.

This method allows for full emotional expression:

• Be honest — Write down every detail of the hurt and anger you feel. Don’t hold back or try to be the bigger person in this draft.
• Identify the cost — State what holding onto this resentment has cost you, such as your peace of mind or sleep.
• Decide the ending — Since the letter isn’t meant to be sent, you can shred or safely burn it to provide a symbolic sense of closure.

5. Focus on self-compassion.

Sometimes we hold onto resentment because we think our anger holds the other person accountable. In reality, resentment only impacts the person carrying it. Shifting your focus to your own wellness is a powerful way to reclaim your peace.

• Prioritize your needs — Focus on activities that make you feel grounded, such as hobbies or rest.
• Practice self-kindness — Treat yourself with the same empathy you would offer a friend.
• Reconnect with your goals — Remind yourself that you deserve a life defined by your own values, not by the actions of those who hurt you.

Letting go of resentment is not a gift you give to the person who hurt you; it is a gift of freedom that you give to yourself.

When anger and resentment may signal a deeper concern

Occasional anger is part of being human. However, it may be helpful to seek support if these emotions:

• Feel constant or difficult to manage
• Lead to frequent conflict or withdrawal
• Interfere with work, relationships or daily life
• Occur alongside anxiety, low mood or emotional overwhelm

In some cases, persistent anger may be associated with underlying conditions such as anxiety disorders, depression or trauma-related responses. A licensed mental health professional can help assess what you’re experiencing and guide next steps.
