Still studying Lisa's illness. Trying to understand it. Found this "Often lonely and isolated, the shopping experience provides the shopaholic with positive interactions with salespeople and the hope that what they have bought will improve their relationships with others.

Shopaholics also have a tendency to be easily influenced by others."

And this "The ability to fantasize is stronger in shopaholics than it usually is in other people. There are several ways that fantasies can reinforce the tendency to buy too much. The shopaholic can fantasize about the thrill of shopping while engaged in other activities; they can imagine all the positive consequences of buying the desired object, and they can escape into a fantasy world to escape the harsh realities of life."
