How can I?

How can I have feeling when I don't know if it's a feeling?
How can I feel something if I just don't know how to feel?
How can I have feelings when my feelings have always been denied? Oh no, oh no.
How can I give love when I don't know what it is I'm giving?
How can I give love when I just don't know how to give?
How can I give love when love is something I ain't never had? Oh no, oh no.

You know life can be long and you got to be strong
and the world is so tough sometimes i feel i've had enough.
Oh no, oh no.

-- JOHN LENNON
