Take me back When it was Just you and I All night long Shooting stars My guitar Playing all of your favorite songs Pretending we're okay These words I wanna say I see it on your face so I don't I know if I ask you won't Tell me what I want to know Since you don't love me Since you don't love me anymore All that we could be Thrown on the floor Tell me where have you been? My serotonin My serotonin My serotonin Fell from Eden, I'm not sleeping Fell from Eden I'm not sleeping Tore my heart and now I'm scarred Tore my heart And now I'm scarred Pretending we're okay Those words I'll never say I saw it on your face now I know Since you don't love me Since you don't love me anymore All that we could be Thrown on the floor Tell me where have you been? My serotonin My serotonin I can't live without you Even if I tried to I can't live without you Even if I tried Even if it tried Even if I tried to I can't live without serotonin I can't live without My serotonin Love me anymore all that we could be thrown on the floor Since you don't love me anymore All that we could be Thrown on the floor You're my serotonin Tell me where have you been? My serotonin I'm not happy without you I'm not happy without I'm not happy without you I'm not happy without you
