Those of us who were raised in chaotic, abusive, or neglectful families can experience lingering effects. Whether a parent had a mental illness, abused substances, or was otherwise unable to provide a safe, stable, and nurturing environment, developmental trauma can occur. Events that happen to us during formative years (particularly emotional abuse/neglect) affect brain development, personality structures, and ways we view ourselves and others. As such, difficulties with emotional regulation, interpersonal relationships, and a negative sense of self are often present and chronic. We can find ourselves repeating unhealthy patterns.
