It's not easy

I can't stand to fly
I'm not that naive
I'm just out to find
The better part of me

I'm more than a bird
I'm more than a plane
More than some pretty face beside a train
It's not easy to be me

Wish that I could cry
Fall upon my knees
Find a way to lie
About a home I'll never see

It may sound absurd
But don't be naive
Even heroes have the right to bleed
I may be disturbed
But won't you concede
Even heroes have the right to dream
It's not easy to be me

Up, up and away
Away from me
It's all right
You can all sleep sound tonight
I'm not crazy
Or anything

I can't stand to fly
I'm not that naive
Men weren't meant to ride
With clouds between their knees

I'm only a man in a silly red sheet
Digging for kryptonite on this one way street
Only a man in a funny red sheet
Looking for special things inside of me

It's not easy to be me

This song (Superman by five for Fighting) has been playing in my head for the past week or so. Though this song is written from the Clark Kent point of view, I feel I could relate to some of the lines - marked in bold. Sometimes I feel it really is not easy to be me. By the way, who am I?!
