1. Using Erikson’s model, briefly explain Sally’s situation.
Within Erikson's model Sally is in phase 4, which is characterised by the central conflict of "Industry vs Inferiority", the psychological strength to emerge through this phase is competence. Sally has currently developed a clear sense off inferiority and is unmotivated to face challenges. She is not tracking to resolve the "conflict" of this phase and there are strong indications negative outcomes from previous phases have compounded (mistrust in relationships, lack of confidence in her abilities,..) While we don't know a lot of context, I would assume that she might have experienced harsh criticism instead of nurturing and encouragement, leading her to withdraw from challenges, mistrust in relationships and generally low self-esteem.
2. How might you approach working with Sally as her counsellor?
I would look at all 4 stages and try to nurture the virtues from the bottom up: hope, will, purpose, confidence. Starting with a safe, positive and playful space to build relationship and trust, consistent and without pressure. I would lean on her comfort in drawing to explore what sparks her and support emerging interests to develop will and purpose.
