How can anyone ever make any progress in Alcoholics Anonymous if they can't express their real feelings?

I've been hanging around the program for three years. But it's phony. You have to put on a happy face and pretend you're happy in the rooms. Anyone who says anything negative, even if it is what they are really feeling, is pretty much shunned. The members call it stinkin drinkin thinkin. But how can a person be Mr. Happy all the time? How can a person possibly fake happiness all the time? I mean, feeling up and feeling down are normal feelings. People should feel down once in a while. It's just natural. It's just not natural to put on a fake show for people all the time. Hence, my problem with program. If you change your way of thinking and you turn into a happy robot who is spitting out positive slogans about recovery all the time, then that just really isn't natural or good for your mental health. You know? Am I making any sense here?
