Cry yourself a river if you can because it only through that tear coming out of you that you can truly settle into a life that is depression free.
Create a cry time and use the tears as a punctuation time for your sadness.
For the past years, this has been my way out of depression(though it's a reflex action). You can't imagine how fast and magical it works. Thanks for this article @ejemai, cos I used to think it was abnormal when I cry like that... I can still use other ways of getting up off depression mentioned above and also mention it to people when needed
