sleepy

I just got home from school and I am so sleepy. I am tired from work this morning and I never got a chance to take a nap today. I was always yawning while I was listening to my teachers but I could not help myself. Now that I am home I would like to go to bed but I have more homework to do. My math class drives me crazy. I could not figure out the problems. My friends at work were helping me my math problem but I still do not understand. I tell myself that maybe I cannot learn anymore. I am so frustrated right now and I need to learn. Maybe I should go to bed and sleep now so my mind can relax and solve the math problem tomorrow.
