Smile and laugh! Who cares! Dont take this condition so seriously :) Try a different routine if you are concerned about breaking and cracking the dead skin layer on your lips :)
I dont have the breaking and cracking of dead skin problem, because I exfoliate every morning and all day long :)
It sounds like you have disconnected yourself from your emotions, the only way to start feeling them again is to start smiling and laughing again, even if it is just faking it :) Ever hear that expression fake it untill you make it?
