Side Effects

I don't know which one it is
 Is it you, is it me, who's addicted?
 'Cause you're the one who wants the fix
 But I'm the one who needs to fix it
 It's toxic, ironic, the way that we fit
 Stuck in a battle that nobody wins
 It's killing us slow
 The longer we go
 You get the rush
 While I rush to save you
 Fill up your cup
 While mine's empty trying to change you
 You're smoking me out 'til I'm on my last breath
 I'll give 'til I got nothing left
 You get the high
 I get the side effects
 I hate that I'm so damn attached
 The prescription to all of your issues
 When your heart gets racing too fast
 You're calling and I can't refuse
 It's toxic, it's costing all my energy
 If I didn't love you, you'd be my worst enemy
 You get the rush
 While I rush to save you
 Fill up your cup
 While mine's empty trying to change you
 You're smoking me out 'til I'm on my last breath
 I'll give 'til I got nothing left
 You get the high
 I get the side effects
 I'm helpless from helping
 You get back on your feet again
 So hopeless from hoping
 I'd ever be enough for you
 And I've never been
 You get the rush
 While I rush to save you
 Fill up your cup
 While mine's empty trying to change you
 You're smoking me out 'til I'm on my last breath
 I'll give 'til I got nothing left
 You get the high (you get the high)
 You get the high
 And I get the side effects
 I get the side effects
 I get the side effects
 You get the high
