"its only up to me to decide"

Its should be It's :)

I have to say, my favorite part about this poem was the ending. I love how you summed this feeling up with saying you always have you - and that is the most important thing. You must love yourself..VERY strong ending.

I love the sense of self worth you have here. It's like you're saying "I am who I am, if you don't like it, tough!" It's a very strong and smart mentality!
