Very first song I've ever wrote, I think it's crap though but can you please tell me what you think :)

It's called "Dreams" It was inspired by Disenchanted and My friend Pat (That's his nickname xD) but I guess to really get it I need to tell you what I want to do? Well I want to join the marines. Yeah Im a girl wanting to fight for a country, but I need to go to the US as the Scottish marines don't let girls in -_-

"I'm gonna tell you what I want,
If you disagree, i don't care
Because I'm gonna go far with this,
It's gonna change my life forever,
But I don't care because this is what I want.
You tell me "no" every single day,
But I ain't backing down on this no, no, no
This is me a d what want I may die but this is my decision,
Not yours no, I'm gonna show you what I'm made of,
this is going to be my last stand.
I'm setting off on my life now,
I wave goodby as I see figures as I pull away with lots of other teenagers,
Looking scared but I'm full of happiness,
Happiness that others won't understand
You tell me "no" every single day,
But I ain't backing down on this no, no, no
This is me a d what want I may die but this is my decision,
Not yours no, I'm gonna show you what I'm made of,
this is going to be my last stand.
The shots that are fired,
The ones that miss me,
But only that one hut me and took me down,
It took me down like a knife on the edge,
Dear mother I am sorry.
