Here I would like to tell you that depression is not sad all the time, and we are no different from ordinary people. The only difference may be our worldview. Our attitude towards the world is different in the early stage and later stage. Our world is not all sad. Of course we may be better at experiencing sadness and creating it. For example, I am not in sadness. Usually you don't feel sad without thinking about it. But depression just makes you lose the ability to stop yourself from thinking wildly.
If you want to watch it, watch it, if not, go away.
