Numb, shutting out world,
chasing it away with doubt.
Used to be deep - but something
happened. Lost myself in thoughts
of life, looking at the world
differently.

Able to see what is ahead,
not behind me. Seems pointless,
being alive within a dream.

Screaming deep inside, yet
silence prevails - Words can't
express what I feel, yet words
are used to describe my emotion.

That's an example of your poem using only one 'I'. Be creative, the English language is pretty flexible in usage - so long as you do so intelligently.
