Letra de Back of my mind

All behind this smile
it´s always in the back of my mind
thought i made it through the hardest of days
sometimes you don´t get back what you gave
i´ll try to rise
i´ll try to call
i´ll try as hard to continue on
but it´s always here, all the time
always there in the back of my mind
always in the back...
of my mind
the back of my mind
i am not the same
because, because of my...brain
