Depression and life

When depression hits
There is no life
Merely a sad existence
Only heaps of strife
Sadness becomes the norm
There is no upside
Only crawling; like a worm
Everything is difficult
Can't even answer the phone...
Too bad if anyone calls
Too bad if you need someone
It's like no-one
Even wants to come
Until there is a knock
Upon your barred door
Then you force yourself
To get up out of that chair
To walk that short 
Distance to the door
Your voice is listless
As you ask
"Who is it?"
Resignation in your voice...
"What do you want?"
The next words to escape
Your dry throat
Was that your voice?
Is that what it now sounds like?
Flat and lifeless
Just like you...
