Your childhood affects the way you think as an adult. You subconsciously learn a significant amount in your earliest years, and these experiences shape your values and behaviours. Traumatic events suffered at an early stage in life, can emerge through behaviours in your adult life, through triggers. These traumas can range from PTSD to anxiety, or in more subtle behavioural quirks, and may even form physiologically in the form of ailments. These traumas can also lead to self-limiting beliefs in children that are demonstrated as they become an adult.
Although recently there has been more emphasis on reaching out and getting assistance, this may limit a significant portion of the population, such as people suffering from self-limiting beliefs from trauma who may struggle with taking any steps to reach out for help. A response to trauma is avoidance, the unwillingness or fear of confronting their demons and this may lead to a person either running away from their problems, or not having the capacity to self-reflect and understand how their past traumatic experiences affect their behaviour. This inability results in the person not being able to challenge their belief system, leading the childhood trauma to continue its manifestation.
