See, I don't see them as the same in any way other than her having a couple of the same traits as Bipolar (moods, sleeping around, shopping, partying) but nothing else about the illnesses even match up. People with these disorders deal with delusions, hallucinations, depression, suicidal ideation.. they are in a fight for their LIFE.. People with personality disorders are in a fight for control.
What I was saying was that each member in a family unit is different from any member of another family unit..... different children, spouses....that kind of stuff and with different personalities comes different reactions, etc.
One family may cope one way. Another family another way and then children within the same unit can each react in different ways. So the dynamic is always changing. The individual with the disorder will even react to the disorder somewhat and sometimes in some ways like the way they are being reacted to - which can be a myraid of reactions lol.
I am speaking to family structure more than the individual I guess.
