School Life running along with motherhood

Most of you know I went back to school full time to finish my teaching degree. I am getting pretty good grades all A's and one B (Biology). Sometimes I feel so overwhelmed with all the school work, house work, and I feel like I am not spending enough time with my girls. As I seat here typing this I am looking at about 15 pages of bio that I should be doing and a couple loads of laundry which need to be folded and put away, and then my girls are running around the house wanting me to play with them!!! Please pray that God will give me strength and the energy to be the mom and wife I need to be.
