You could maybe research places they could go, provide things for them to "do" to show them another way of being? "Habits" have to be replaced with better/different behaviors or they'll just come back. My favorite example is of a guy that wanted to stop biting his fingernails so placed nail files everywhere in his house where he sat and started the habit of filing/caring for his nails instead. At the end of the 21 days it takes to either make OR break a habit, he had a new habit regarding his nails. If you have other friends or groups you go to, etc. bring your friend along to meet new people or find a new place you both can explore together, etc. and she won't have to go back to what's familiar?
