I think, by putting commas around the borrowed words/sentences it should be ok...I would call it wordsmithing. Having said that...when you also use your own..it's making the poem slightly busy looking right now. I know you want the reader to pause in between Me, Myself and I but you could always use my little favourite (...) for this? This probably wouldn't work if you are trying to separate the characters I know as you speak of them in past tense and they seem to have a separate identity from you right now...hope you know what I mean...you are speaking in third person and past tense all rolled into one?
It needs a bit of work IMO but...it was an interesting read....just needs a little tightening up here and there...maybe a bit of a haircut in some lines :)
I do love Eleanor Rigby BTW..one of my favourite songs.
This is very unique, although kind of awkward to read with the beginning of the sentences start with "Me" and"myself" instead of I ...but I definitely understand what you were going for, and it works...just not used to reading in third person, I suppose. :) The repetition of using me, myself and I work really well, so good job.
I think you are trying to use the "Me" and Myself" and "I" as three different people, especially caught onto that in the 'I' is burned out and lazy, going crazy, changes, changes, changes, it's never easy." ... because if you were meaning yourself, you would say 'I' AM burned out and lazy ...and so on.
I think I'm beginning to confuse myself by trying to explain... I hope you will understand and know that I know what you are saying by this poem, but I just can't write it properly in this damn comment. Haha
I like the addition of the bits and pieces from Eleanor Rigby ... it gives it character.
Overall, a really nice piece of work. I like something that is very thought provoking and makes me think outside the box.
