This is a really good start! I love the last two lines the best. However, I think you could really add to this, and maybe change the order of the stanzas around. As it is, your thoughts seem a little unorganized and don't flow as well as they could. Another, smaller thing- You have some places where you use the wrong their,there,and they're.

Wow this was nice. you portayed the emotion well. though it was short and the flow wasn't great, but otherwise another great poem.
