I am a mother of four. I am attempting to complete a pre-med bachelor's degree in Anthropology and hoping to someday attend medical school. I feel a little foolish, crazy and overwhelmed at times. I question my sanity and stamina. I wonder if I am being selfish by trying to fulfill my dreams of becoming a doctor while being a mother. My kids definitely feel the strain of finals and late-night cramming. How much is too much?
