I just started playing guitar and was wondering if anyone could play this song on guitar

I originally tried it in "F", but now I think it is "F#"

So now I was wondering if there was anyone out there that knew the tabs/chords for this song cuz I'm all confused

I tried looking on line but the one I found didnt help me

I'm thinking the chorus is:

F(barre) C Bb
My only hope, my only peace
C Bb F(barre)
My only joy, my only strength
C Bb
My only power, my only life
F(barre)-Drop 6th String
My only love

but as I was saying I think it's up a half-step

Any tips/tricks to playing this song (yes I know there are 2 guitars in it) would be GREATLY appreciated

thanks a lot

Joe
