You don't know where she lives, but yes, no matter where she lives, she should certainly have a roommate.
A colleague of mine, very well-known and respected in her profession, lived a nice life: single woman, nice house in Palo Alto, regular European travel, great car, etc. etc. Then, she came down with fibromyalgia and was so sick that she couldn't work anymore. It was a bitter pill, but she took in a roommate, cut out the European vacations, and cut out all the luxuries, etc.. What was particularly unfortunate was the the way the whole ordeal changed her. This strong confident woman became really whiny and self-pitying and difficult to be around. The illness and all the adjustments she had to make must have cratered her self-esteem.
