Not quite a depressing song, but very emotional for me, as it signifies me, in such a way that makes me wish.... You know.

Eminem: Not Afraid.

E.G.:

“You can try and read my lyrics off of this paper before I lay 'em
But you won't take the sting out these words before I say 'em
Cause ain't no way I'ma let you stop me from causing mayhem
When I say I'ma do something I do it,
I don't give a damn what you think,
I'm doing this for me, so *censored* the world
Feed it beans, it's gassed up, if it thinks it's stopping me
I'ma be what I set out to be, without a doubt undoubtedly
And all those who look down on me I'm tearing down your balcony”

Yep. That feels like me. 'Cept I can't do any of the tearing bit, unfortunately, or possibly fortunately.
