Depression has a different quality than the normal range of sadness that you may feel throughout the day. When you are depressed you do not feel like being with anybody. You either sleep way more than usual or you can hardly sleep at all.

Your energy level goes way down and you have a feeling of hopelessness about life

I’m scared of all those voices
Inside my head.
They scream to hell.
They could bring me to death.
I can’t let them win.
But i’m just so tired.
So tired of this life.
So tired to fight.
I just want to let go.
Close my eyes,
Take a deep breath,
And sink into unconsciousness.
After all,
Wasn’t I born to die?
