|Hi. Tmt. This is an excellent poem. I personally like the concept of addressing depression in a poetic genre which leaves a seemingly endless amount of possible directions you could take the work. To me the work flows quite nicely and keeps me engaged. The progression of the poem with lines such as "the pressure builds" & "And yet" keep my attention and make me anticipate the next line.
There is one aspect to your writing that I think might make an interesting change to the impact of the poem on your readers. That is the variation or the switching from the literal to the metaphorical sense in two specific places in the poem but then leaving the literal aspect to close the work.
To explain: The poem itself is surrounding a whole ensemble of human emotions. You begin with "feeling depressed, state of mind, coming out, pressure builds, so many thoughts, spiritual self" and alike. To me this is the main driving aspect of the work it invites me or rather compels me to immediately emphasize with the message you are trying to convey and you have my complete attention. Also, your last two lines: "But they are glued together by my flesh - indefinitely" are awesome!
What pulls me back from being totally immersed in the poem are two very specific lines "Security walls made of thick metals" and "Brain and skull."
I would simply like to suggest that using a metaphor for these lines or removing them completely may give the poem even greater strength. Consequently if you do decide to implement metaphors they should work in direct relation with the powerhouse conclusion. A literal line as contrast to emphasize your impact on the reader.
I envision to be something like:
If your depressed - (Great introduction, I'm engaged)
A state of mind - (I'm searching my emotions)
Blocking anything - (My anticipation builds)
The pressure builds - (I'm engaged even further)
Wanting to escape - (I'm confirming my desire)
Uninterested in your spiritual self AND They wish to be freed - (Nice transition leading me to the literal from the emotional)
But are glued together by my flesh - (A sledgehammer finish bringing the reader into the literal)
Nice writing my friend.
I look forward to reading more your work.
