What's the word for "can't express myself clearly"

Music in the background
Thoughts in my head
Stars in my eyes
Still awake.

Is this all i will ever be?
A dreamer in his fantasy?
Will i ever wake up and try getting there?
But everywhere is where i wanna be?

I want nothing but the best
But can i get the best of everything?
Is it too late to start?
Then the song on the radio goes

"If u never try u'll never know
just what u were.
Lights will guide u home
And ignite your bones.
I will try to fix u!!!"

Good night!! !12.07 a.m.
