:] I like the opening statement. I think the command came as a surprising element. Then you made another statement right after (X is not Y) you stated an opinion but you're supporting your belief strongly and further stressing that it goes NO WHERE. The whole piece shows attachment and persistence; as though you are writing for your own self or for someone who you care a lot about.
As for the emotional part of your poem, my ill heart agrees and disagrees, it's sometimes subjective. But no, I know you are right. Separation from what is destined will take you no where. It's worse than prison and worse than a dead end alley, it's like being stuck in a whirlpool. You can't move on, you can't let go, you will always be stuck.
