The money thing - if the lawyer said it as an insult or in a libellous fashion and it has caused your friend damaged feelings you can sue them.
I’ve heard people saying “ugh they have a personality disorder” when they mean “they have an attitude problem”. It’s very damaging and insulting to those who have personality disorders and face stigma. It perpetuates a myth.
My relative was downright evil and wanted to destroy everything, she had Narcissistic and Histrionic Personality Disorders and other psychiatric illnesses - there is a high rate of co-morbidity.
I have colleagues and other people in my life with Borderline Personality Disorder and Avoidant PD. A couple have been very difficult, most have been lovely, hard working, good parents and friendly etc. There are a lot of myths out there about PDs. They almost always happen due to very sad beginnings in life. I even have sympathy for my evil relative despite enduring almost 30 years of abuse from her. Nobody chooses to have a PD. It’s an illness. Not an insult to be bandied about.
