And some song lyrics, 'cause I've felt like this a few times:

Swing, Swing, Swing by All-American Rejects

Days swiftly come and go.
I'm dreaming of her
She's seeing other guys
Emotions they stir
The sun is gone.
The nights are long
And I am left while the tears fall.

Did you think that I would cry,
on the phone?
Do you know what it feels like,
being alone?
I'll find someone new

Swing, Swing, Swing from the tangles of
My heart is crushed by a former love
Can you help me find a way
To carry on again.

Wish cast into the sky
I'm moving on
Sweet beginnings do arise
She knows I was wrong
The notes are old,
They bend, they fold
and so do I to a new love.

Bury me
(you thought your problems were gone)
Carry me
(away. away, away...)
