“I Did an Unforgivable Thing as a Kid.” 5 Tips for Dealing with Childhood Guilt

Feeling horrible about what you did at a young age, thinking, “How could I have behaved that way?” This article will help you address childhood guilt and regret.

If you’re wondering whether difficult childhood experiences may still be influencing your thoughts, emotions, or relationships today, take a childhood trauma test.

How to Deal with Childhood Guilt in Adulthood

Although childhood is supposed to be a carefree and happy time, children can also make serious mistakes, hurt others, break rules, lie, act impulsively, or behave in ways they later feel shame for.

Guilt and regret rarely disappear because we repeatedly tell ourselves to “stop thinking about it.” Fighting intrusive thoughts does not resolve them. A better way is to reflect on the experience without repeatedly analyzing it [1] American Psychiatric Association. Rumination: A Cycle of Negative Thinking. March 2020 .

1. Name exactly what you regret

Instead of thinking, “I’m terrible” or “I’ve ruined my life,” focus on identifying the specific behavior.

Ask:

• What exactly did I do?
• How old was I?
• What did I understand about the situation at the time?
• What did I not understand?
• Was I acting intentionally?
• What circumstances surrounded the behavior?
• What do I understand now that I didn’t understand then?

2. Separate responsibility from identity

You can take responsibility for something without letting it define your entire personality. Acknowledge it honestly: “I did something I regret. It affected someone. I wish I had acted differently. I understand more now than I did then. I can use what I’ve learned to become a kinder person today.”

Wondering whether rumination and replaying past events can be a sign of obsessive-compulsive disorder? Take an OCD test to learn whether you may be experiencing symptoms associated with OCD. 

3. Ask what the regret can teach you

When regret becomes a lesson, it can help you become the best version of yourself. Perhaps the experience taught you to:

• treat people more carefully;
• think before acting;
• respect boundaries;
• apologize when necessary;
• protect vulnerable people;
• control impulses;
• recognize the consequences of your behavior.

4. Don’t punish yourself as proof of remorse

You don’t have to turn regret into positivity immediately. Sometimes the healthiest response is simply: “Yes, I wish I hadn’t done that.” Remorse can be evidence that your values have developed.

However, sometimes people discover they use guilt as a form of self-punishment because they believe they don’t deserve to feel happy.

5. Talk about the memory

Childhood guilt may be more difficult to process when it remains a secret [2] Fine NB, Ben-Zion Z, Biran I, Hendler T. Neuroscientific account of Guilt- and Shame-Driven PTSD phenotypes. May 2023 . Sometimes saying the words out loud, such as “I did this when I was a child, and I still feel terrible about it,” can be the beginning of separating the past from the person you are today.

Talking to someone you trust can help you see the memory from a different perspective. A qualified mental health professional can also help if the memory causes distress, shame, anxiety, or intrusive thoughts.

How Do I Forgive Myself for Childhood Mistakes?

You may look at your younger self as if they were a smaller version of your current adult mind. However, a child doesn’t possess the same:

• emotional regulation;
• life experience;
• impulse control;
• understanding of consequences;
• ability to recognize manipulation;
• perspective-taking abilities;
• independence;
• knowledge about relationships

that an adult has [3] Fan L, Kang T. Early childhood trauma and its long-term impact on cognitive and emotional development: a systematic review and meta-analysis. July 2025 . Here’s how you can practice self-forgiveness.

1. “Advice to the Child I Once Was” Exercise

Try imagining that a child you care about came to you and said, “When I was young, I did something awful. I’ve hated myself ever since.” Would you tell that child, “You deserve to hate yourself forever”? Probably not.

You would likely want to understand what happened, acknowledge the harm, help them learn, and remind them that they are more than their worst moment. Self-compassion asks you to extend this humanity toward yourself.

2. “Two Letters” Practice

Writing to your younger self creates distance between who you were then and who you are now. Instead of judging your childhood from an adult perspective, this exercise invites you to approach your younger self with curiosity and compassion.

1. Letter one. From your adult self to your younger self

Imagine the child you were sitting in front of you. You know everything you know now, but they do not. They are still learning to understand themselves, others, and the consequences of their choices.

Tell them what you wish they had known at the time. You might write about what you now understand about their situation, what they could not have understood then, or what you wish an adult had told them.

Try to acknowledge the things you regret without turning the letter into another punishment. You might begin with, “I know what you regret. I also know that you were still growing.”

Then continue in your own words. Tell them what you wish they had known about mistakes, responsibility, forgiveness, guilt, or being loved. If they were struggling with something you now understand differently, tell them that, too.

2. Letter Two: From Your Younger Self to Your Adult Self

Now reverse the exercise. Imagine that your younger self could see you today. They know what happened, but they can also see everything that came afterward. They can see the person you became, the things you learned, the relationships you built, and the ways you changed.

What might that child say to you? Write a second letter from their perspective.

Perhaps they would ask why you are still carrying something they did so many years ago. Or, they would tell you that they were scared, confused, or simply didn’t understand. Maybe they would ask you to stop being so hard on yourself.

Let the child’s voice be imperfect. You don’t need to force it to be positive or forgiving. If sadness, anger, confusion, or fear come up, allow those feelings to exist.

Where Does Childhood Guilt Come From?

Childhood guilt can develop from ordinary mistakes, family situations, school experiences, or the feeling of having disappointed someone.

The Effects of Childhood Guilt

Some guilt is completely normal. It teaches children that their actions have consequences and helps them recognize harm and learn how their actions affect others. It can also contribute to the development of empathy. A child who realizes that they have hurt a friend may feel guilty, apologize, and learn from the experience.

However, guilt becomes harmful when a child begins to believe that they are responsible for things they cannot control. Instead of thinking, “I made a mistake,” they may begin thinking, “I am a bad person.”

Adults who experienced excessive guilt as children may struggle with:

1. Low self-esteem
2. Fear of making mistakes
3. Difficulty setting boundaries
4. Constantly apologizing and people-pleasing
5. Fear of disappointing others
6. Overanalyzing and overthinking past mistakes
7. Feeling responsible for other people’s emotions

When Childhood Guilt Becomes a Mental-Health Problem

Persistent guilt can sometimes occur alongside depression, anxiety, trauma-related conditions, obsessive-compulsive symptoms, or other mental health conditions. Consider seeking therapy if replaying your childhood mistakes:

• occupies a large part of your day;
• causes severe anxiety or depression;
• prevents you from enjoying your life;
• makes you believe you don’t deserve happiness;
• causes repeated compulsive checking or mental reviewing;
• leads to self-hatred or self-punishment;
• interferes with relationships;
• causes thoughts of harming yourself;
• It feels impossible to control, even though you know rationally that the event is in the past.
