Silent killer

Never a warning. 

It creeps up slowly

Stalking, 

Whispering,

And then all at once,

It pounces

It takes over

Possesses.

There doesn't need to be a reason

It can come anytime

The happiest day of your life

And it could come slithering in 

It cuts your mind; a knife

There is no escape

Only delaying. 

It's drowning in a desert,

Screaming in a crowd of people

And no one hears. 

It's suffocating in an empty room.

It's catatonia. 

It's horror

It's pain

It's sadness. 

It's depression.
