The guitar part in the beginning was influenced by Cuban Composer and Classical Guitarist Leo Brouwer’s Simple Etude #6. The two riffs (Rhoads' and Brouwer’s) are very similar.

[Verse 1]
Screaming at the window
Watch me die another day
Hopeless situation
Endless price I have to pay
[Chorus]
Sanity, now it's beyond me
There's no choice
[Verse 2]
Diary of a madman
Walk the line again today
Entries of confusion
Dear diary, I'm here to stay
[Chorus]
Manic depression befriends me
Hear his voice
Sanity, now it's beyond me
There's no choice
[Bridge]
A sickened mind and spirit
The mirror tells me lies
Could I mistake myself for someone
Who lives behind my eyes?
Will he escape my soul
Or will he live in me?
Is he trying to get out
Or trying to enter me?
[Guitar Solo]
[Verse 3]
Voices in the darkness
Scream away my mental health
Can I ask a question
To help me save me from myself?
[Chorus]
Enemies fill up the pages
Are they me?
Monday till Sunday in stages
Set me free, oh
