Why Boundaries Are So Hard After Trauma or Abuse
For survivors of abuse (neglect, emotional, psychological, physical, sexual) saying “no” and setting boundaries can be extremely difficult. This is because your nervous system may still be stuck in childhood survival patterns such as: hypervigilance, fawning, or dissociation.
We are not born with strong boundaries, they develop gradually with guidance from our caregivers who ideally protect, respect, and role model healthy limits for us. But if a caregiver is inconsistent, unsafe, or abusive a child learns that their “no” will never be respected.
This is because in abusive environments, survival always overrides making yourself heard. Saying “no” may result in violence, punishment, and withdrawal of love, so learning to suppress your boundaries becomes the safer choice. This is not a conscious choice, it’s a survival strategy that confuses your developing sense of self with the need to stay safe.
Your nervous system is designed to detect threat and keep you alive. When a child faces abuse, their body automatically goes into an instinctive survival response depending on the situation and this may take the form of:
Fight: resisting or fighting back (often too risky for a small, vulnerable child).
Flight: trying to escape (often impossible for a child who has no access to resources).
Freeze: shutdhttps://caroline-king.co.uk/understanding-trauma-how-the-freeze-response-affects-healing-and-recovery/own, dissociation, or numbing out.
Fawn: trying to please the abuser to reduce conflict.
For children, fawning often becomes the dominant response, because it increases their chance of survival in a relationship they cannot leave. Agreeing, complying, and being “good” keeps the abuser calmer, which may reduce immediate threat and harm, or prevent worse outcomes. It is also a way to maintain some connection which is necessary for survival.
Trauma bonding
From birth we are biologically wired to bond with our caregivers – they are essential for our survival as our source of food, shelter, and safety (however inconsistent). So even if the parent is abusive, the child must attach, suppress boundaries, and appease because their survival depends on it.
And when abuse is mixed with intermittent care or affection, the traumatised child’s nervous system becomes stuck in a cycle of fear and hope. When the abusive parent is the cause of harm and the only source of care, the child’s brain can associate love with feelings of pain.
“Loving” the parent, even if it’s harmful, is not optional – it’s the nervous system’s way of staying alive in an impossible situation. This “love” is survival-driven attachment and becomes a way to maintain some sense of stability. It’s also why many children believe the abuse is their fault. If they love the parent, and if they’re “good enough,” then they’ll finally receive safe love in return. It’s how the nervous system prioritises survival and attachment over truth or safety.
When your early survival wiring tells you that it’s not safe to say “no”, fawning becomes your default. Knowing this may help you to understand why you’ve struggled with boundaries. Your nervous system has learned that boundaries equal danger and that saying “no” risks punishment or abandonment.
This is why survivors often struggle with boundaries later in life, because in relationships the habit of appeasing or people-pleasing, becomes the default as your body learned that this is how to stay safe.
When your boundaries are crossed, your body experiences an intense stress response, including a surge in cortisol (your body’s primary stress hormone), increased heart rate, and muscle tension. This surge can keep your brain stuck in a constant state of high alert, making it difficult to think clearly, or make decisions and regulate your emotions.
When you feel like you’re stuck in emergency mode, it can lead to isolating yourself. This is counterproductive to your nervous system’s built-in need for connection. Our ventral vagal state is also known as the social engagement system. Being in a ventral state means that our nervous system feels at ease and connected and we can experience feelings of contentment and calm, or even excitement, joy and playfulness.
Healing involves teaching your nervous system safety. When it feels safer, you are more able to set and maintain boundaries. This helps to lower your cortisol levels and create a sense of predictability that calms the amygdala (your brain’s threat detector), and allows your prefrontal cortex (the part of your brain that’s responsible for planning and decision making) to work more efficiently.
Each time you set and maintain a boundary, your neural pathways are strengthened, making it easier for your brain to regulate your emotions and say “no” in the future. Over time the neural pathways you use more become more efficient and the less-used pathways weaken.
Feeling safe, rather than being stuck in a constant stress response, supports the health of your body’s homeostatic functions such as hormones, temperature, fluid levels, blood sugar, pH balance, blood pressure and removing toxins from the body.
Boundaries are not just about personal comfort; they are essential for your nervous system health, stability and wellbeing.
