Work Life Crises

I have an issue, can anyone suggest to me how i can manage my time better! I now have to practically run the family business on my own (with ageing parents) I have two children under the age of five and of course don't forget the husband, who would at times require some attention! ;) I feel guilty, leaving my kids, they are still soooo little, i'm going crazy...... There is no such thing as relaxing weekends anymore, due to the fact of phone calls on my mobile from employees. Does anyone know of any kind of super hero, who can come and save the day!!!!! ;)
