Dude...your poem only lacks structure at the first place....!!!
I liked the feelings emoted,the wordings used should have been just a little bit more poem-like and other than that I would suggest you to cut the stanzas into much small and fragmented verse and put in commas,full-stops to accentuate reading and with a little bit of tweaks,your poem would just be fab...:)
I hope to read more from you as your poem has honesty...:)
