Inchoate song

I love singing and writing songs. I've written more than a dozen of songs, but for some reason i'm not being able to complete this group song at all. I've just got here so far!

i've tried it every time
have never backed down
i'm built to go ahead
as they've always said

i'll never let you down
will always be around
to see if your Okay
and i know i can say

Give me your hand and
i'll lead the way
i'll be your light and
i'll show you the way

Chorus:

Just give it away
just let it be
i'll be your sunshine
believe in me
