I'm a slave of my heart
following his whims
binded by his feelings
stuck on this chaotic cycle
of suffering and happiness
frustrated by failure
excited with victory
always unstable
always confused
always in love
and someday I know
It'll probably vanish
this feeling, all of this
will all be a memory
just untill love raptures me again
then the cycle restarts...

(It came out this way, very raw and spontaneous, no worrying with rymes too.)
