Read the following excerpt from Edgar Allan Poe's poem "Alone" and answer the questions that follow:

"From childhood's hour I have not been
As others were; I have not seen
As others saw; I could not bring
My passions from a common spring.
From the same source I have not taken
My sorrow; I could not awaken
My heart to joy at the same tone;
And all I loved, I loved alone."

What is the speaker expressing about his childhood and emotions in the first four lines of the poem?
