Analysis of Forbidden

How can I exist in the same world as that brightness?

When my nights and days are so dark.

There's more to me than what they see,

I’m nothing but a pretender wearing a mask.

Without it I’m nameless and faceless,

no identity at all,

to the one who matters most.

If only she knew what I felt inside,

how my knees got weak when she passes me and with just a slight glance she would make my heart melt.

How do I even begin to explain that smile and how it shines bright like the sun!

If only I was worthy enough to be in "her world" I would find a way to tell her one day,

but on the other side of the divided middle line in "our worlds" it just doesn't make sense.

Which brings me back to my original question: how can I exist in the same world as that brightness?!
