Hey I understand that lack of energy and motivation, I usually have it myself and feel so reluctant to do many things, I just can't be bothered any more and don't care (well I do care, just not enough!). I know the point your mother's trying to make, because my dad thought along similar lines when he found out about my depression. It does work in a way because it forces you to do things rather than retreating into yourself and into total apathy.
