Whenever you meet someone you greet them and then the next question is : How are you? The obvious answer is: I'm fine, thank you! There was a time when i used to get pissed and just said: Are you asking me because you really want to know (as in: you are concerned and wanting an elaborate answer) or you are just waiting for the classical "I'm fine thank you!" ?
So, now whenever people ask me how i'm doing i just say: " I'm fine!" with an emphasis on " fine"; so if they want to know more, they will get the explanation: F.I.N.E. Freaked-out, Insecure, Neurotic & Emotional
This is totally not mine ... but Hezzy's (i learned it from her!).
