I think this needs editing...

Feels I was running.... AN ENDLESS MILE!, why can I not leave this behind?

maybe insert 'like' between feels and I

apart from that I liked the way that you capitalised some of the words in the poem to stand out and to truly express to the reader what you have always wanted to scream out loud. I find this an important and powerful technique as you make clear to the reader what the underlying message is.
