She reminisces about how in Flatbush she was able to get around even though she didn't drive, but in lakewood she can't.
Maybe this is the place to start then, asking what she would be doing now in Flatbush if she were still there, to get a better idea of just what it was that kept her from feeling bored.
Was it going to particular places, like a park, shopping, meeting friends? That would give you some ideas of the kind of opportunities to suggest in Lakewood.
Or was it the "getting around" that she misses? That is, not just being in a store, which your family probably drives her to now, but the time she spent walking to and from the stores, getting some exercise, seeing people, window shopping, watching the hubbub. If so, maybe she could find one or more walking partners, some women who'd appreciate having an incentive to get up and take a walk, but who also have a car so could drive to varying places to walk - a different neighborhood, along the lake, a shopping district.
Or was it the freedom to make her own schedule that she misses? In Flatbush she could go shopping whenever she wanted, while now presumably she needs to coordinate with ride-giving family members. If that's the problem, then maybe you could set her up with uber or some local equivalent, so that she feels more able to go where she wants, when she wants.
