How common are personality disorders?

And one must be definitive about what constitutes a "disorder". Co-dependence is extremely common but not necessarily debilitating. ADHD is also very common but most people function OK.

Depression is more debilitating and is common. I estimate one third of the population has some kind of personality disorder but less than 10% are so affected as to be unable to function and lead a "normal" life.... whatever that is.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
