From the sheet music at Indiana University:


ALL BY MYSELF
Irving Berlin
New York: Irving Berlin Inc., copyright 1921

1. I'm so unhappy! What'll I do?
I long for somebody who
Will sympathize with me.
I'm growing so tired of living alone.
I lie awake all night and cry.
Nobody loves me; that's why.

CHORUS: All by myself in the morning,
All by myself in the night,
I sit alone in a cosy Morris chair,
So unhappy there,
Playing solitaire.
All by myself I get lonely
Watching the clock on the shelf.
I'd love to rest my weary head on somebody's shoulder.
I hate to grow older
All by myself.

2. My name and number are in the book,
The one that hangs on a hook
In almost ev'ry drug store.
Why don't someone bother to look?
My central tells me all day long:
"Sorry the number is wrong."
