Hey, this is definitely your best!! Nice work!!

Very nicely done. I am not a poet at all, though I appreciate reading it. I think it a rather lovely work, unique and sentimental.

how sweet.. nicely written!

I like this a lot. The whole theme of bravery and pain is common among anyone who has loved ones. You want to be brave when they are away when we feel we can't go on on our own. As a poet, I might add that you would want to seperate the poem into stanzas.
For example:

I got this line
This line goes next
Probably have another
See how I outline the text?

That's basically what I mean. Also, it would be good to add some periods too. You don't want the poem to be one big run-on sentence. In any case, keep up the good work. I look forward to reading more of your stuff.
