Angela,

From your description, I would suspect that she has some kind of personality disorder, and it will probably be very hard for anyone to get her to change the way that she interacts with people. She will probably seem very needy, and no matter how much help you give her, she will always find another problem for you to help with. She could benefit from learning to do her own problem solving, but she's not likely to be motivated because it isn't solutions that she wants. Having someone listen to her is the solution to her, but it never lasts.

The best way to deal with people like that is to get really good at setting your own boundaries. If you need to, you could get some assertiveness training (either in individual counseling or a workshop or other group). While the problem is hers, the only way to deal with it is by dealing with whatever part in it is yours.

Good luck!
