I don't know anything

Somedays I feel
like I don't know
what another days
I am so sure of,
somedays everything I feel
is second guessed,
sometimes more than once,
but really I don't know
I just have your word to go on.
I say you love me all the time
but who am I to say that
it's not me feeling the way you feel,
I only know what I feel,
I don't know anything at all
I say everything will be fine
but who am I to say that
I don't know whats going on
now, or in the past to effect today,
I don't know anything at all,
I say in ten years time
we'll still be together,
but who am I to say that,
I can't know what you're going to feel
and I don't know if we'll have wounds to heal,
I don't know anything at all,
No, I don't know anything at all
