My first poem since I was a teenager.

[SummerRose]

I'm very embarrassed to post this. It's my first post, and my first poem really, and it's so very depressing that I'm certain it's emotional drivel... But perhaps even critique of drivel can help..?

Anyway:

I have felt despair.
The yawning, aching chasm at three o clock in the morning
And certainty, amid my doubt,
That this cannot be borne.

And then the loss of words,
Communication lost in soundless, shapeless scream.
Horrors emerge in understanding
No one else can know.
And all I can explain is this:
I have felt despair.

The morning comes, the dawn
That brings relief; in every song and script,
Despair gives way to hope, in life
to dread, and horror at the thought:
Night will return.

Reason maintains a feeble grasp in light,
While strong, despair lies dormant, confident, aware.
Waiting for my mind.
Waiting for my life.

Hi there. Here's my novice opinion. I like your first line, "I have felt despair." It draws curiosity.This is personal preference but I hate the use of "and" to start a line so I would say "then comes the loss of words."
I'm not really crazy about the fourth stanza. I sort of like "night will return" as an ending. Maybe the concept in the fourth stanza can be re-worked somewhere else, not sure. Anyway, good work!
