I realize some of these lyrics are taken out of context but they express well how I am feeling.

Oh, and twisted thoughts that spin
Round my head
I'm spinning
Oh, I'm spinning
How quick the sun can, drop away
- Black, Pearl Jam

Father snores as his wife gets into the dressing gown
Picks up the leter that's lying there
Standing alone at the top of the stairs
She breaks down and cries to her husband
Daddy, our baby's gone
Why would she treat us so thoughtlessly
How could she do this to me

She (We never thought of ourselves)
Is leaving (Never a thought for ourselves)
Home (We gave her everything money could buy)
She's leaving home after living alone for so many years. Bye, bye

-She's Leaving Home, Beatles

Well she went up to her room where she sang her faithful tune
Well I'm goin where those chilly winds don`t blow

-Rain and Snow, Grateful Dead

Pink Floyd
"Goodbye Cruel World"

Goodbye cruel world
I'm leaving you today
Goodbye
Goodbye
Goodbye
Goodbye all you people
There's nothing you can say
To make me change
My mind
Goodbye.
