What they don't tell you, is that you don't need to be depressed to want to end your life.
You don't need to think that your life is over.  
You don't need to think that everyone hates you.
You just need to have a crippling fear and anxiety over everything you have and haven't done in the next few and last few days.
It sounds like simple stress.
But what they don't tell you, is that sleepless nights and days without meals and unrealistic expectations add on you, and pile on you, until you're breaking from hysteria.
Hysteria is all you need to **** yourself, although they don't tell you that.
Just absolute conviction that you just want to go to sleep and never wake up.
It doesn't matter how happy you are, it doesn't matter how many good things are going in your life, it doesn't matter how selfish you're being.
All it takes is the inability to drag yourself out of bed to face another disappointing day.
All it takes is a little bit of meaningless sadness.
All it takes is hysteria, weeping, and conviction that you don't want to see another day.
You may not ever act on suicide, but that doesn't mean that a part of yourself hasn't died....but they won't tell you that.
They will never tell You that.
