Sweetener

I don't know what I want but I know what I don't
I could stay play it safe but you never let me go
I'm not a quitter but I'll leave you bitter
Only want me to stay 'cause you can't be alone
('Cause you can't be alone)
But I can't be the sweetener in your coffee
Sugar rush when you want me
Try to keep you up all day, all night
It's so exhausting
I can't be your, can't be your sweetener
