self contained, self content?

it's just a thing.

self contained and self content
no promises to keep
i got myself so together now
that i just can't fall asleep
walked the night
and drank the moon
got home at half past four
i knew that no-one marked my time
as i walked through my door

it's really lovely to discovert
that you'd like to be alone
not to owe your man an answer
when he gets you on the phone
not to share a pair of porkchops
when you crave champaign and cheese
your aims become to please yourself
and not to aim to please

give it to me now

oh they sold me
when the told me who could live as cheap as one
now i'm learning
twice you're earning doesn't mean
it's twice the fun
you spend each day and half your life
on someone else's dreams
and every night is one more fight
cuz money changes everything

it's really lovely to discover
that you'd like to be alone
not to owe your man an answer
when he know that you ain't home
and the thing that drives you crazy
is your own sanity
you smash your mirror, you just wanna sleep forever
but you wake up and scream

look out

take a deep breath
try not to slip
that bottle of pills on the floor
gonna make your trip trip trip trip trip trip trip trip trip
