i agree with lots of what has been said for what its worth i think that it comes from a melting pot of ideas ,even if you say aha that is my label what matters is how you deal with life .i can at the moment diagnose myself with a depressive/dependent personality but i feel sure this will alter slightly .i find at 51 my ideas are still evolving i feel it is about growing awareness of my strengths and weakness and living with limitations,there is no use myself becoming a salesperson as i don't have the strength to do it,though could i do it if i had to do it? no probably not ,i am coming round to seeing that we all have a part to play in the drama of life ,at times it feels like a joke a friend of mine a psychiatrist said once to me that personality disorders are just labels made generally by men in suits they can help in treatment strategies but dont forget the human being.i think our personality is made up of both nature nurture with social economic factors i call it my melting pot theory,as if i just believed in one thoery i'd have to do a lot of defending of it!!!
