IMHO, the difference between this and suicide is that suicide is often done on impulse and over a temporary manner, such as a breakup or what not. Most people will get over a break up, but the initial shock can be rough. Rough enough for some people to take their own lives. If they had just taken a night out and a good nights rest to think it over, they probably wouldn't have killed themselves.
This woman, on the other hand, can not move, and all she has time to do is think... think all day long about it. Her decision was not made on impulse, but over a long period of time of uncurable pain, agony, and it attacked her pride. It is hard to draw a line, but I think there is a difference.
