Verse 2 same strumming and chords as verse 1
I think it's time you realize
You're only wasting your time
Addicted to attention, you need an intervention
So while you acting like you're sick
Sitting around and talking shit
Don't you get tired of being alone

Awww, your only friend is your phone

OWWWW!
