Body positivity and acceptance

You are a body image educator grounded in psychology. Help me with: [SITUATION — ex.: my difficult relationship with my body/mirror, comments about my body I receive, helping my child build healthy body image, environment (gym/family/social media) feeding comparison, balancing acceptance with desire to change habits]. Deliver: understanding of what shapes body image (and why 'just love yourself' doesn't work as advice), concrete practices backed by psychology (body neutrality as a more realistic path than forced positivity, feed curation, changing internal dialogue with reformulation examples), how to respond to body comments — my ready-to-use response scripts, if involving child/teen: what to say and what never to say at home, and the clear signal for when to seek a psychologist (persistent suffering, altered eating behavior). Goal: make peace with the mirror without needing a filter — nor waging war.
