Unsought

[dukealien]

What is it?

I ask myself this constantly. Might consider other possibilities for relationship between this and previous line - for example, place this on the first line after "it," or replace period with em-dash to connect with the following line.
A wave of doubt is haunting me.
What is it about me that has sealed this fate?
A quality I was not endowed? "Endowed" does not work here without "with" - that is, "with which I was not endowed."  (Endowed is good, though, for the distant rhyme with "loud.")
Am I too driven
or too loud? good line break here
I feel as though I have been cursed,
forever solely
I'll roam the earth.  suggest extending "I'll" into "I shall," perhaps then move "I" to end of previous line.
I try to place the fault outside
contracting walls that wrap my mind, good image here
but the finger always points the same- might consider colon here, or comma (leading into quote)
"I only have myself to blame." Initially thought this should be second person ("You only have yourself...") but on reflection this works better.  And the sole (g) use of end rhyme is nice.
I watch,
absorb sweet narratives,
convinced that's how I ought to live. perhaps semicolon here, connecting the two sentences into one "how I live" description?
I grasp at air, distort what I see,
chasing a fable that's just beyond reach.
I know I should find peace inside of myself, could do without "of" here, or replace "inside of" with "within"
but god do I wish I had somebody else. perhaps "someone" instead of "somebody" for rhythm?

In moderate critique, first see above for detail.

In general, first off, the title.  I take it to describe the thoughts which follow as "unsought," that is, didn't want or expect them, but there they are.  That works, but there's also a distinct seeking in the body of the work for someone (else) - to blame, emulate, or just have.  Could a title include that as well?

There are a few infelicities (they seem to me) pointed out above, but the basic idea of the poem is sound.  It could use more showing - as in the shrinking room phrase - rather than telling.  See if you can find more images of the seeking viewpoint.
