Sorry for taking so long to welcome you to the forum.
It's astounding how damaging munchausens syndrome is to families as a whole. So much lying, so much manipulation, so much hurt and hatred. Even the people who are uninvolved in any of the medical stuff get caught in the crossfires.
That's interesting, regarding your family passing it down with each generation. I really wish there was more research on this disorder (or factitious disorders as a whole) to fully study the impact it has on family systems.
I'm in a bit of the same situation in terms of family relations. With the exception of one person (my grandmother) everyone thinks of me as some terrible, hateful person. Everything I've said must be a lie, right? Arg. Emotionally it's easier and healthier for me to step away from them as much as possible.
Hang in there.
