They explore internal polarizations between critical and escape-seeking parts. They unpack neuroscience links to Internal Family Systems, the role of compassion, how therapy reshapes patterns, and practical ways to access calm, curious self-energy.

ANECDOTE

High Functioning Cocaine Use Linked To Childhood Pain

  • Marc Lewis describes a client whose cocaine use gives him strength, focus, and relief rooted in childhood confusion and family dysfunction.
  • The example shows how high-functioning people with jobs still develop intense cravings tied to early emotional wounds.
ADVICE

Use Self Presence To Lower Defenses

  • When supporting someone, shift to self-energy: state I'm okay, I'm here, I'm open, I love you to lower their defenses.
  • Cece Sykes uses this neutral, compassionate stance to invite the person's concerned parts to surface without judgment.
INSIGHT

Phones Create Shields That Block Loneliness Work

  • Smartphones increase stimulation, isolation, and preoccupation which amplify protective parts and block feeling loneliness.
  • Cece Sykes relays treatment-centre observations: young clients finish groupwork then retreat to their rooms and phones rather than engage socially.
