Between Love and Exhaustion: A Qualitative Study of Greek Parents’ Lived Experiences Supporting Adult Children with Substance Use Disorders

<b>Background/Objectives:</b> Parents of individuals with substance use disorders (SUDs) often carry significant emotional and relational burdens, yet their voices remain underrepresented in addiction research. This study explores how Greek parents navigate the long-term challenges of caring for adult children with SUDs, with a focus on emotional strain, caregiving identity, and culturally embedded coping strategies within a collectivist context. <b>Methods:</b> Eight Greek parents (six mothers and two fathers, aged 47-60) participated in in-depth, semi-structured interviews. Conversations were conducted either in person or via video call, depending on participant preference and geographical constraints. Data were analyzed using Interpretative Phenomenological Analysis (IPA) to explore lived experience and the meaning-making processes shaping parental coping over time. <b>Results</b>: Four overarching themes were identified as follows: (1) Living in Vigilance, reflecting constant hyper-alertness, emotional exhaustion, and social withdrawal rooted in trauma; (2) Shifting Parental Identity, capturing the evolution of parents into caregivers, advocates, and informal caseworkers amid systemic neglect; (3) Struggling Within Systems, highlighting exclusion, blame, and fragmentation in institutional care-with moments of empathy holding outsized emotional weight; and (4) Coping as Cultural Duty, showing how caregiving was sustained through values of sacrifice, loyalty, and protective silence, even at great personal cost. <b>Conclusions:</b> Greek parents supporting adult children with SUDs face a complex interplay of trauma, cultural obligation, and institutional strain. Their coping is shaped by deeply held familial values rather than access to effective support. The findings call for culturally attuned, family-inclusive interventions and further research into long-term caregiving across diverse contexts.
