How do you deal with burnout?

Burnout and depression turned my life upside down a few years ago, I went from an ambitious high-performer to a lucky run if I get out of bed. I remember hating everything related to a career and goals that I used to love, feeling empty inside, really empty, I'm not talking metaphors here. It is a feeling that I do not wish on anyone. With ups and downs, sometimes feeling very accompanied and sometimes very lonely, I managed to recover after many attempts. I managed to love what I do again and change my meaning of success, of what I want and how. Those who have been through it know that it is a before and after. Since my recovery, I decided that helping this not happen to anyone else would be part of my life goal.
