Frozen - Sick And Tired lyrics

I feel a worse day is coming on My hands are shaking and my teeth grind Feel a bit responsible for it all And I wonder if there's something I could have changed, Changed I do this I do this all the time now I worry I knew it all along I hate it I love it for a while I miss it It's better to forget it Sick and tired Down to the wire Cannons are ready to fire On this heart I pay my dues, paying them all of the time What do I do? Taking up part of my mind Sick and tired Down to the wire Cannons are ready to fire On this heart I do this I do this all the time now Worry Knew it all along Hate it Love it for a while Miss it Better to forget it Better to forget it
