Depression has seriously affected work and life, how to mediate?

Life is different every day. We can't have everything, everything goes well, and depression is always inevitable. First of all, you can't take depression seriously. Think about it. If you are in high spirits every day and your nerves are always in a state of excitement, you should worry about when your nerves will collapse, right? Therefore, we should treat depression with a normal heart. With the right attitude, you can say anything. Moreover, if the mood is depressed to the point of discomfort, then we can't bear it. I usually choose a person to find a quiet place to listen to a particularly sad song and cry. If I can't cry, then I think I have to read a particularly sad novel or try a movie again, so I can usually vent here. If I have tried all these methods and still can't relieve my mood, I will pack up and keep encouraging myself: "I am at the lowest point in my life, so no matter which direction I work hard, things will get better and better." Or, "If the sky is to become a great task for the Sri Lankan people, they must first suffer from their minds, bones and muscles, starve their bodies, empty their bodies and mess things up." This famous saying inspires me and warns me.
