i hate college

I was waiting for the count down to midnight on my birthday but I decided to check my grades before midnight... I failed one of my classes because my professor never graded my final. It was turned in on time, turned in a second time a few days later, neither version was graded. I emailed her twice about it but I haven't gotten a response and my first email was before final grades were out, just notifying her about my assignment in case she forgot about it but I just sent the second one a few minutes ago asking about my grade and my ungraded final. I spent weeks working on an 11 page research paper just to fail my whole class because it didn't get graded and there's nothing I can do about it. It's my birthday in 15 minutes and I'm sitting at my laptop crying because all the work I put into this class was for nothing and I'm gonna have to retake it, and to top it all off, all my rental books are overdue because they made the due date the day of my last class that went until the library closed but I thought I had until the official end of the semester, which would have been this week. Genuinely losing my mind right now, this is gonna be an awful birthday. Starting off my 21st stressed out and crying.
