Yes, depression comes in stages. Just like in the world of finance and markets, the world doesn't immediately fall into depression, it first has a recession and then drops into a depression, so also, we human beings first go through stages of stress, worry, fear, anxiety, and when all these accumulate, they keep sinking us into a valley of sadness and then ultimately, we become depressed. Depression is that state of extreme sadness, of worry, fear, anxiety, pessimism. Therefore, we should stop it when it starts. We should not reach that stage of depression.
