being overwhelmed with children and work

As a mother of seven children ranging in ages from 16 years to 4 months old, I am always on the go. It seems as though I never get a break. I juggle between being a driver, a referee, cook, teacher and housekeeper while I am a home. I barely have time for my husband. With the birth of my youngest son, who is now 4 months I am not working outside of the home. At the age of 32, I find that I feel much older than my age. I got married at fifteen, with my parents consent and had my oldest daughter immediately. With encouragement from my parents and husband I managed to finish high school and eventually graduate from a four year university. I worked hear and there while continuously having babies. The bulk of the financial responsibility fell on my husband. While the responsibility of the home and children all fell on me. I find that through my religious beliefs I am able to stay calm. People always ask me, "how do you do it?" i can only give credit to God. I get my strength from God. So when you are stressed pray and ask for strength from God. It works for me.
