Depression is as real as the air we breathe. It is that feeling at that moment that you wish life will take away your breathe.
Depression can be triggered by even the slightest event, it turns a happy moment into a gloomy one. A depressed person can be in a room full of people, video games and internet yet lost in that deep hole.
It's okay to feel down at a point in ones life but how you pull yourself out is the most important thing.
Speak out, don't be ashamed to let it all out. You're human too.
