Playing with Connotation - Depression

[Buck]

I aligned it to the left so the editing could look better.

It’s dark, there’s no place to go. Not sure you need "It's" or "there's" - obviously you want to keep your own voice, but I think distilling the language a bit gives the poem a more stark feel, which is what I'm getting from the sense of all the other lines.
No place to turn, no place to hide.
My head is screaming, can’t escape. Not sure you need "is" here
My emotions numb, can’t feel a thing.
The pain inside, won’t erase.
My body limp, won’t progress. I don't like the repetition of "won't" in this and the previous line. Maybe you could try "can't" in this line?
My thoughts are poison, to myself. Try "My thoughts, poison to myself." It sounds much more distilled and concise.
The hole is deep, too profound.
I’ve hit the point, of my despair. Were you trying to make "I've hit the point" both a reference to the speaker's despair but possibly also to a knife point i.e. suicide? Because if so, I'd leave the comma, but if not, take the comma out.
Inside I cry, of my own tribulation. [/b]This line does not fit the rhythm of the rest of the poem. Too long - try "Inside I cry of my own affliction." Sounds smoother and the reader still gets the meaning

I've never liked center alignment of poems. Seems too similar to the Hallmark Card-type poetry, which is all too awful to think about. This is an overall good poem, but the formatting makes me shudder.

Your line breaks make sense, and you keep them consistent.

Work on distilling some of the language. Some of the lines work fine already and don't have unnecessary baggage, but most others need some condensing.

Your adjective and verb choices are fine.

Some of your comma placements are trouble spots, and lead to confusion or destroy the flow of the poem. You don't need to have a comma halfway through the line for the sake of having it there if it doesn't work all that well throughout.

It's a pretty good poem though. Nice imagery and good theme throughout.
