Have you ever viewed old photos or had a thread of thought such as: What happened to me? Difficult experiences can trigger changes to one’s thinking, feeling, and reacting patterns for many people, such as increasingly being on edge, being subservient to others, or becoming withdrawn or irritable. One of the common inquiries is, “Does trauma alter your personality?”
The answer is yes. Trauma can have an impact on our personality, emotional reactions, relations, and even the manner in which we see ourselves and the world. These changes, however, do not indicate damage or “broken.” When referring to changes in personality related to trauma, many times they are actually protective mechanisms that are developed by the brain and nervous system in response to experiencing an overwhelming amount of trauma.
Learning more about these changes can serve as a foundation to make the individuals aware of what’s happening and open the door to healing. Please note this article is for information only and is not intended to diagnose or treat.
What Does It Mean When Trauma Changes Your Personality?
Personality refers to the patterns of thoughts, emotions, behaviors, and reactions that shape how a person interacts with the world. Traits like confidence, emotional openness, trust, patience, sociability, and emotional regulation are all part of personality.
Although personality can feel stable, it is not completely fixed. Major life experiences, especially traumatic ones, can influence how these traits appear over time.
Trauma has an impact on parts of the brain involved in:
- Emotional regulation
- Memory
- Fear and threat detection
- Stress responses
- Relationships and attachment
With excessive stress to the nervous system, adaptations might occur that promote safety and survival. These protective patterns can start to seem like it is a permanent personality shift as time goes on.
For example:
- Once an outgoing person may turn into a withdrawn person
- Someone who is normally calm can experience a greater stress response and become easily irritated
- A trustworthy person might become overly guarded in their feelings and adopt great precautions
These responses usually happen in an attempt to avoid the commitment of more pain or danger.
Can Trauma Permanently Change Who You Are?
Trauma has left many feeling ‘different’. The brain’s capacity to change is continually evidenced, though there is the capacity for long-term emotional effects from trauma. This is called neuroplasticity.
Don’t expect to be the same person you were before the trauma! Instead, recovery often involves:
- Feeling emotionally safer
- Regaining connection with yourself and others
- A point for reflection and reconnection with self and others
- Identifying healthier coping strategies to use
- Reducing fear-based reactions
- Restorative measures to raise confidence and trust
If a person receives the right care and attention, they will end up being emotionally more balanced, healthy, and genuine.
Common Signs Trauma May Be Affecting Your Personality
Some personality changes that occur as a consequence of trauma may be subtle and happen over time, impacting all areas of life, relationships, work, and emotion.
Becoming More Withdrawn or Isolated
Emotional or social withdrawal is a frequent trauma reaction. You may become unable to talk to someone, avoid attending gatherings, or perhaps not trust people as much as before.
Things that you used to enjoy or do easily could now become emotionally demanding. Others start cutting themselves off and don’t understand what is happening. Other people start to isolate and are not really aware of it.
Increased Irritability or Emotional Reactivity
The nervous system can turn those who have been injured into a hyper-alert state. Small annoyances can come across with greater intensity of feeling for this reason. You may notice:
- Being “on a schedule” more frequently
- Speaking to loved ones with a snapping voice
- Becoming overwhelmed quickly
- Emotional state of ‘on edge.’
It does not mean you’re an aggressive person; it may just be an overactive survival mode in your nervous system.
Emotional Numbness or Detachment
Trauma reactivations are not the only ones who are emotionally “on,” others respond by shutting down. People may feel like they aren’t connected with others, cannot find enjoyment, or feel unmotivated to react emotionally.
This is a type of emotional numbness that somewhat exists as some kind of protective mechanism of coping, so that you don’t feel emotional pain.
Difficulty Trusting Others
Relationships and attachment can be greatly impacted by trauma. You may:
- Avoid certain individuals because of anxiety, not to be close to them
- Fears that they’ll lose their love or will be abandoned or betrayed
- Have difficulty with the concept of being safe emotionally
- When feeling clingy, reject or move away from the person
- Push people away even when you want a connection
Trust issues often occur following betrayal, something that warrants trust, but was neglected or abused, criticized, or relationships were unstable.
Negative Changes in Self-Image
Trauma may impact the person’s identity. Others unconsciously share an exaggerated sense of criticism within themselves or hold on to a more intense sense of shame, guilt, and worthlessness.
Feelings are likely to revolve around the following thoughts:
- “I’m not worthy of God’s love.”
- “I feel that I am not safe.”
- “There’s something wrong with me.”
These beliefs have a tendency to go along with hurt feelings and a lack of factual truth.
Why Trauma Causes Personality Changes
Trauma alters the way that the nervous system ‘knows’ what is safe. The brain shifts to protecting rather than relaxing, connecting, or being open.
These can establish longer-lasting trends like these:
- Hypervigilance
- Emotional avoidance
- Fear of vulnerability
- Difficulty relaxing
The child’s reaction to stress is heightened. Many of these behaviors actually start to cope with an emotionally challenging circumstance. In the long run, they can negatively affect relationships, work, parenting, and general well-being.
Childhood trauma has a particularly significant impact, as during the early years, the emotional control system and personality processing are still maturing.
How Trauma Can Affect Daily Life
Although personality change is a common occurrence following trauma, it can focus not just on emotions.
Struggle to deal with aspects of work at the workplace that cause them difficulty, including:
- Confidence
- Speaking up
- Leadership roles
- Burnout
- Perfectionism
When it comes to relationships, some side effects of trauma include:
- Emotional distance
- Conflict avoidance
- Fear of intimacy
- Jealousy or insecurity
- Difficulty communicating needs
Trauma can go up for parents:
- Overprotectiveness
- Emotional exhaustion
- Irritability
- Concerns about kids’ safety
These patterns are often puzzling or even rage-provoking since it can be recalled that the person was “different” before the stressful times and events.
Can You Heal from Trauma-Related Personality Changes?
Yes. Healing is possible.
Many people experience improvements with the appropriate support in:
- Emotional regulation
- Self-esteem
- Relationships
- Stress tolerance
- Confidence, capacity to feel secure, and a sense of belonging
In trauma-informed therapy, individuals can gain a better understanding of how their survival reactions started to manifest and better strategies on how to maneuver typically. Often recovery takes place slowly and bit by bit over time.
Healing may involve:
- Safely analyzing traumatic experiences
- Learning skills for settling into the party
- Skills of settling for learning
- Rebuilding self-trust
- An overall shift towards lessening nervous system hyperarousal
- Practicing emotional regulation
- Establishing healthier ways to relate to others
- Creating healthy relational patterns with others
The recovery of the nervous system can also be aided by supportive lifestyles – following a regular sleep pattern, exercise, meditation, and engaging with peaceful environments.
