A case study highlights the use of rapid tele-psychotherapy with single-session music therapy (RTP-SSMT) as an effective intervention for a 22-year-old woman experiencing hopelessness, depression, and suicidal thoughts following a breakup. The broader context emphasizes the urgent need for appropriate mental health interventions for young people facing terminal issues like depression and suicidal ideation. The girl’s condition was characterized by fragility and a lack of motivation, common among her generation. RTP-SSMT proved successful in reducing her feelings of hopelessness and depression. The findings suggest that RTP-SSMT could be a valuable tool for mental health professionals seeking to support patients dealing with similar emotional challenges after relationship difficulties.
