I know quite a few in our hall who are "Bi-Polar-Rollers" - the fakers who have to leave after the public talk, sit out in the hallway with a heard of hugging sisters, they leave just before TMS and miss many meetings. Add to that they have to eat like pigs in FS (yes, I have had to stop at McD for some bloated faker to gorge on a couple of Big Macs because her "BP was acting up" stupid me thought it meant blood pressure) They get pissed off at you for no reason and blame their Bi-Polar.
Sadly, those who genuinely suffer from it never broadcast the fact and quitely go about their lives - of the 3 - 4 we have there is one geniuine Bi-Polar and this sister is a gem - we would help her out in a heart beat.
