March 2021. The world has been living its third great war for a little over a year. The arrival of the coronavirus, a hidden enemy that causes a serious and highly contagious disease, forced people to change their habits of life. This work focuses on discussing the psychological effects of the social isolation that has become necessary since then and the loss of predictability of life projects, factors that affect mental health. Without the group conviviality and the control over the future of their activities, human fragility becomes evident. However, the work also wants to recognize the need for reconstruction through a new project of happiness based on the search for meaning in life.pMarch 2021.
