Noooooooooooow I get it completely dear Mari...
My family is excactly the same... you know, when you ask them how they are, they always said fine even when the family is breaking in a million pieces... And of course, I have to reply the same thing because, they dont like to listen problems, illness... the real stuff you know... they just pretend... you said it right...
My mom for example, is even pathetic.... she doesnt like medicines, and under that principle, she thinks every doctor exaggerates when giving medicines...

So, of course, Im fine, Im normal, I dont need medicines, I dont have mental issues... I dont have sleep problems, is just that I drank coffee... and yeah, Im always "fine"...
Oh well... I even feel sorry for them... I mean, I LOVE to talk about my problems so I can listen to others and learn from their experiences and advices, and nobody in my family wants to listen, less they want to talk...

I dont know how can people live with all those "secrets"... I would explote one minute or another...
