Empty the full cup and you'll be free

Someone once said to me
Empty the full cup and you'll be free
Memories please leave
and let me be in peace

Albert from Hitch once said
If being miserable is the only way to stay connected
then being miserable is who I'm supposed to be
but is that the right way to go
Is that the life I'm supposed to live

Too tired to think
Everything is now so confusing
but that phrase keep popping
Empty the full cup and you'll be free
