Does anyone know if this is song lyrics or a poem? If so can someone tell me who it’s by or the name and if I can find the meaning

Im afraid

although I like to mask my fear

I prefer to stand clear

tall buildings mountain tops

or simply just a roof

I imagine the worst

I tremble and even sometimes curse

it's very common to fear

but I prefer to not let my friends hear

as I feel they may make fun

I'd rather suffer instead of run

it may not come when you're young

climbing trees and riding rides

until you feel the fear

and then riding those rides may be hard

lots of courage to ride once more
