I just dont know

At first I saw nothing,
Then I saw a blur,
When I found out you had cancer,
I didn't remember if there was a cure.

I didn't know if I could tell you,
I didn't know if I had the heart,
I didn't know if I could handle it,
My world felt like it was falling apart.

We always went somewhere,
Each and every Friday night,
We would get mad at each other,
But we never considered it a fight.

I never thought her life,
Would be taken away from her so soon,
We always would talk about,
How we wanted to go to the moon.

She will never see me happy,
She will always see me cry,
Because I know my best friend,
Will soon be doomed to die.
