The LOW KEY youth exchange aims to provide young people with a safe and supportive space to explore mental health and well-being in depth. In the partner countries – Slovenia, Lithuania, Serbia, and Spain – young people face similar challenges: school pressure, social expectations, feelings of loneliness, stigma around mental health, and limited access to professional support. The project seeks to create an international environment where young people can connect, share experiences, and find common solutions, while strengthening their personal competences for dealing with everyday challenges. The project originates from the needs expressed by young people themselves, volunteers, and participants in youth organizations, as well as from an idea developed during the international training KEEP IT REAL in Lithuania. Through various non-formal learning methods – workshops, debates, reflections, creative activities, physical movement, and work in nature – participants will develop competences in emotional regulation, learn to recognize their feelings, and practice strategies for coping with them. At the same time, they will contribute to destigmatizing the topic, which is still often considered taboo, and foster a supportive culture based on acceptance and empathy. The objectives of the project are multifaceted: to empower young people to recognize and articulate their struggles and seek help in time; to improve their emotional resilience and self-confidence; to raise awareness about the importance of mental health among young people and in their communities; and to contribute to creating more inclusive and supportive youth environments. The project is aligned with the goals of the Erasmus+ programme in the areas of inclusion and diversity, participation in democratic life, digital literacy, and intercultural dialogue. A key feature of the project is the active role of young people. They will not only participate but also initiate and co-create activities – taking responsibility, preparing workshops, writing articles and posts, recording a podcast, and implementing dissemination activities in their communities. In this way, they will become ambassadors of change, spreading messages about the importance of mental health, destigmatization, and peer support. Dissemination will include presentations in schools and youth organizations, social media posts, articles in local media, and creative campaigns designed to reach the wider public. This approach will ensure long-term impact: participants will develop skills and competences that will benefit them in further education, employment, and active citizenship; partner organizations will strengthen cooperation and networking; and local communities will gain young people who are more resilient, empathetic, and ready to build a culture of openness and solidarity. In the long run, LOW KEY will not only influence individuals but also their communities, national youth policies, and the wider European youth field, demonstrating that sensitive topics can be addressed in a safe, inclusive, and effective way.
