The project "Youth Work together. For Mental Health" addressed the challenges identified by the WHO in the field of mental health problems, considered one of the greatest challenges of the 20th century. Given the increasing number of people directly or indirectly affected by mental illnesses, the project focused on the mental health of young people, with a special emphasis on young people with fewer opportunities and/or disabilities, as well as on the training of youth workers in this area. The aim was to contribute to the preservation of the mental health of young people and youth workers, thereby improving their well-being, which is also a concern of the EU Youth Strategy 2019-2027. As part of its activities, the project tried and developed solutions in areas where health systems and other institutions had not yet established effective structures. The COVID-19 pandemic led to a postponement of the project but also highlighted its relevance even more due to its impact on young people's lives. Moreover, the project aimed to initiate a broader public debate on mental health, especially in networks and areas where this topic is still highly taboo and where those affected experience stigmatization and discrimination. Another goal was to impart skills in the field of mental health to youth workers, advancing the professionalization of youth work and enabling practitioners to apply methods that support both themselves and young people in dealing with their mental health and personal well-being. The project also aimed to provide access to international educational opportunities for young people with fewer opportunities and/or disabilities, a group that is greatly underrepresented in international youth work and faces specific challenges related to trauma, exclusion, and mental health. Participation in mobility measures strengthened the self-esteem of these young people, offered them developmental opportunities, and enabled them to establish contacts with peers from other countries. This exchange and learning with peers from other countries reinforced the feeling of not being alone and empowered the young people through these shared learning experiences. Given the importance of the theme, the project pursued the long-term perspective of encouraging the active participation of the participants in society and their lasting motivation to take part in other educational activities, thereby supporting a functioning civil society and lifelong learning. "Youth Work together. For Mental Health" utilized the Erasmus+ program as a tool to specifically activate disadvantaged groups and contribute to the positive development of young people, youth workers, and youth work in general.
