Overcome your depression

Everyone has time in depression. And how to handle this is a learning. To quote a famous Chinese saying, blessings do not come in pairs and calamities never come alone. I do think it makes sense especially the part about calamities. I don't know how to express this in a professional way in psychology. In my words, I hold the view that if you drifted into sorrow one day, maybe the bad mood would always bother you everywhere. That is more worse. So in order to avoid that, you should distract your attention and look at the bright side of the issue. Through my experience, I draw a conclusion that someone lose things in some way, he will get compensated from other way. Life is balanced. So it's useless crying over spilled milk.
