[Intro]
[Verse One]
You see someone else when you look at me
You see what I ve always tried to train myself to be
You see dinner tables and picture frames and everything in between
You see a medicated mind gripping tight to belief
[Chorus]
And I hope I never have to see this waiting room again
With patients coughing beside me,
while i stare up at fluorescents
Praying that no one I know will walk in
And I ll have to explain why I m here
But I don t even know why I m here
[Instrumental]
[Verse Two]
My mouth sewn shut, for you I tear open the seams
Every time they ask what s wrong with me
If I knew, I d tell you, but trust me I don t
And you can diagnose me, but that won t make me cope
[Chorus]
And I hope I never have to see this office again
Spitting out my demons to somebody I just met
She s taking notes just to remember my name
Cause the only one who listens is the person I pay
And I hope I never have to see this waiting room again... x3
[Outro]
Lest I forget what it s done to my head
Let the medication fix me instead
