How to convince my mother to do some activities?

Adam, did she used to be active in the community, or has she always been something of an introvert? Being introverted myself I can tell you that sitting at home doing lots of nothing is my preference too, and I would resent anyone trying to force me to be something I'm not. That said, there is a difference between introversion and being a complete recluse, does she not go out at all? Could she be suffering from Depression?
