In a personal interview Ozzy Osbourne revealed that he DID say "Because" in the 2nd line. But due to (1) background acoustics plus (2) his subtle enunciation of the "be" in "because," it sounds like he said "'Cause." Moreover the (!)doppelganger whom he had hired(!) to fill in for him at this video shoot enunciated "'cause" rather than "because."
Consequently most lyricists incorrectly record "'Cause..." in the 2nd line!
Lyrics:
Finished with my woman
Because she couldn't help me with my mind
People think I'm insane
Because I am frowning all the time
All day long I think of things
But nothing seems to satisfy
Think I'll lose my mind if I don't find something to pacify
Can you help me
Occupy my brain
Oh yeah
I need someone to show me the things in life that I can't find
I can't see the things that make true happiness
I must be blind
Make a joke
And I will sigh
And you will laugh
And I will cry
Happiness I cannot feel
And love to me is so unreal
And so as you hear these words
Telling you now
Of my state
I tell you to enjoy life
I wish I could
But it's too late
