My smile is sweet You can never tell what I’ve been through 'Cause I stay discreet It’s none of your business if I'm cool I’ll just hide it all away But good God I'm tired I have never felt so dammed rung out I feel expired But none of those feelings can come out I’ll keep them safe under lock and key but This smile gets heavy And no surprise I'm not doing ok This smile gets heavy How can I keep living this way I can never be weak I done held together until now It’s way too easy for me I ain’t built to be broke down But good God I'm tired I have never felt so dammed rung out I feel expired But none of those feelings can come out I’ll keep them safe under lock and key This smile gets heavy And no surprise I'm not doing ok This smile gets heavy How can I keep living this way This smile gets heavy Heavy And when you're lost and afraid My smile will take your pain away It’s ok I’ll be strong I’ll help you carry on But good God I'm tired I'm so worn out I feel expired And if those feelings can’t come out I’ll keep them locked This smile gets heavy And no surprise I'm not doing ok This smile gets heavy How can I keep living, keep living this way This smile gets heavy
