Have you considered that she might be manic-depressive? Her behavior sounds a lot like the behavior of my manic-depressive mother, if you substitute shopping for drinking. Manic-depressives are frequently very resistant to therapy, because while they are in the initial upswing of a manic episode they feel extremely happy and full of energy and happy with themselves to the point of becoming braggarts. How would she react if you tried to stop her hyper behavior. Would she become irrationally angry? If so, that is another sign.
