I fell on my bike going 0 MPH

Yesterday I was heading off to school, this was the day after my 21st birthday and I had a midterm in my anthro. senior seminar class. I was a wee bit tired, to say the least. I was on my trusty bike and before I could make it out of the driveway I straight up fell. My chain came off and I went bam, smack, boom into the telephone pole. I got a bit'o blood on my midterm..woops.
