As far as I know, it's really inacurate to make diagnosis of some mental illness in a person who is dead and cannot by analyzed by a psychiatrist. Of course, a psichiatrist could make an approach of what mental illness and historical character must have suffered from, but it's a great risque. In most of the cases, this specialist could be wrong.
No; I don't think she could have been Bi polar. Maybe she could have been a little depressed at the time of the war, and much more after Revolution beginning...but I think I would have been depressed too. She seems to have been a very sensitive kind of person.
