How much stress can a woman handle?

My daughter and granddaughter has moved in and she doesnt take care of my grandchild( my only piece of heaven) my teenage son is out of control and actually i had to contact defax to learn what i should do & they tell me to leave the home and my husband want work in a pie factory. What can i do? I have a full time job and i cant support everybody on what i make. i ask my daughter for $15.00 a week and she won't even do that. my husband told me i knew how he was and learn to live with it.
