if this person you are speaking of is "deb".... she was, and still is news. "deb" has not changed an iota. still unbalanced - dangerously close to losing it physically, she still confronts people for slights only she perceives.  the fact she was a professor shows how mental illness goes across the board - it doesn't respect  or even acknowledge education, employment, what you had been like previously. she had been relatively high functioning - with a lot of support and enabling sisters, TOO MANY enabling sisters. she is vicious and is remembered. she positively emanated hatred. 
 i wound up in her sights because i was walking with a MAN. who was walking his big MALE dog,  who just happened  to be seen by her...literally - she saw a big male dog and that set her off. before i realized how unhinged this woman was, i tried to reason with her. the words that came out of her mouth, directed at me would have been stuffed right back in but i immediately saw she was pretty sick.
