P.K.
Drop school for now. What's the point. You can't stay awake. Three or four hours of sleep a night. Do you get behind the wheel of a car? If you do, stop immediately before a tragedy occurs. Are you trying to prove something. I don't get it. Take care of your family. School can wait.
Look I believe in bettering yourself, but not at the expense of your kids or others. Driving exhausted is like driving drunk.
This has nothing to do with breast feeding. Wise up Momma.
