Really appreciate the imagery of silent screaming and the frustration which goes along with trying to be heard and to express but being forced, by self and others, to scream!

I see the 'I' and usually my goal is to challenge an author to work on eliminating some, but in this poem it works but I would still say--consider taking out just one...and see where the line goes or the words which come from the absences of the I...

Also, next...write the same poem in a sonnet format and use the end rhyme scheme of ababcdcdefefgg--with the gg being the solution, answer or the continuous of the problem--
The Thurber House is a great forum for educating yourself about poetry writing and a venue for learning about how and where to publish. There is also a really cool place for poets in C-bus where you can go for a retreat or just sit with other poets for an afternoon called the pudding house-- --also they publish a monthly journal with local writers--check them out...
good luck and well done...
