Honestly, it sounds like it's done.. Some poems don't have to be that long to get your point acrossed.. This poem is full of emotion and I really think you should leave it as it is.. It great like this...

you still dint know,
^Don't
Thats the only thing wrong with your poem Just fix that word.. Great work hunny

Oh my gosh........its so exactly...perfect, i think its finished personally but as you dont there is obviously a want and then need to write more. Go, write, otherwise you will just feel its not finished, its really good, dont believe for one second its not worth finishing, i cant wait to see how you make it better (if its possible...) OK blabbering time to post comment!

Maybe draw out the last few lines, and make 'I'll lay alone' 'I lay alone'....
Sorry had to read it again..
