I got your messages on my machine 
 I never called you back at the time 
 I got the flowers you sent to my work 
 With a note suggesting coffee sometime 
    I realise you're thinking 'bout me 
 But I've been avoiding you 
 You don't seem to see what's obvious 
 But it's time some truth broke through   
 CHORUS 
 I'm not your lifeblood 
 I am myself 
 I am not your oxygen 
 You can breathe as well 
 This is obsession 
 This is addiction 
 And how sadly you're mistaken 
 Your beating heart I'm not 
 I am myself   
 This is not about the way you are 
 You were a friend when you had my trust 
 There's notthing wrong with you, as far as I know 
 You just think you need me way too much   
 But this has gone too far 
 I've seen you parking in my street at night 
 Hoping just to catch a glimpse, or talk with me 
 But what you're wanting won't ever be   
 CHORUS 
 I'm not your lifeblood 
 I am myself 
 I am not your oxygen 
 You can breathe as well 
 This is obsession 
 This is addiction 
 And how sadly you're mistaken 
 Your beating heart I'm not 
 I am myself   
 Yeah this has gone too far 
 I've seen you taking photographs of me 
 Don't you know you're scaring me, this has to end 
 You gotta give up this fantasy, oh   
 CHORUS 
 I'm not your lifeblood 
 I am myself 
 I'm not your oxygen 
 You can breathe for yourself 
 This is obsession 
 This is addiction 
 And how sadly you're mistaken 
 Your beating heart I'm not 
 I am myself
