In the year 2020-2021, almost 15% of the Australian aged between 16 to 85 years is found to experience very high level of psychological distress (Loveday et al., 2022). It is also reported that depression among teenagers is a long-lasting condition of sadness where the individual is found to loss interest in work and it also increases the risk of developing suicide(Plana-Ripoll et al., 2019).
