Shackles or Security Shells?

yes, i guess they were shackles that i broke...
but then why do i miss them sometimes...?
why do i think i deserve the pain...?
why is freedom not liberating the way its supposed to be...?
why do i not fly...?
is there no room for me in the sky...?

or is it that i'm afraid...?
that i need a caring hand to guide me...?
to give me the push down the hill so i know i can fly...
make me believe that i HAVE to give it a try...

or does my destiny want me to go back...?
return and burn them on me...
cz thats where i fit...
the land suits me maybe, i've never tasted air...

were they really shackles???
or were they my security shells...?
