Can't say I fake it, but I go through the motions when I can. When I can't, I stay at home or away from people. Luckily I've been able arrange telecommuting with my job. I don't think faking it is a good idea, suppressing emotions is something my T says I should not do. Hasn't affected me in that bad of a way in he past, one time I snapped at a few coworkers and I was approached by HR, they were understanding. I got a little time off. And to my credit the people I snapped at are assholes to everyone, and I got a few pats on the back from others. And I don't get sht from them anymore.

But don't read this and go off on people at your job, you might get fired, lol.
