Invisible shield

Must be more to this
than I'm seeing now
Or is it my eyes
can't tell why or how
Not exactly clear
something isn't right
Fell down on my head
Changing day to night
I need an invisible shield
Mama never told me it would be this way
Stone or paper, concrete or real
To keep from going wild
I need an invisible shield
Mama never said there would be days like this
I need an invisible shield
To keep myself alive
Don't hear what you say
Don't care what you think
There you go again
Living on the brink
Musn't get upset
That's the way things are
haven't seen 'em yet
Wonder who they are
I need an invisible shield
Mama never told me it would last this long
I need an invisible shield to keep me going on
I need an invisible shield to hide something don't know what it is
I need an invisible shield
To save my soul
I really do need it
Can't make it on my own
I need a shelter
Or a ride home
What's that you say
I think I hear you talking
Mmmm mmmm
Birth, death, infinity
Twinkle of an eye
I know you understand it
Don't ask me why
I need an invisible shield
Mama never talked about a woman like you
I need an invisible shield to see me through
I need an invisible shield to stop me sinking all the way down
I need an invisible shield to turn things around
I really do need it
Can't make it on my own
I need a shelter
Or a ride home
