Mostly a good translation.
It would be easier to read if you'd format it in the same way as the original lyrics. And the last paragraphs seem to be missing.
I suppose the lyrics were updated since you added the translation.

Well, there are some grammar mistakes in it, though:

"Because since child,"
That needs to be either "Because since childhood" or "Because since I was a child"

"Mom have taught me that, Mom have taught me that,"
It must be "has taught", and here simple past fits better (only "taught").

"Yo vivía tan distinto,
algo hermoso, algo divino,
lleno de felicidad,"
I think a more literal translation would be
"I lived something so different,
something gorgeous, something wonderful,
full of happiness."
