One Word

This word has ten letters

That cut away at my sanity

This word is like a drug

It ruins my life

Each letter individually brands itself into me

So that I will always remember them

The word pushes away who I love

And tells me that all I need is it

The word tells me I'm okay 

Then throws me off a cliff

This word is already tieing the rope around my neck

So that I don't have to do it myself

This word affects many

I just so happen to be one of them

This word, this dangerous cause, is

Depression
