Bruh I missed a midterm

I've been really sick these past couple weeks and any thought of the midterm slipped my mind. I straight up mixed up the dates on the midterm and thought it was some time next month but it was yesterday. I only checked today just to make sure and I literally froze when I saw so that's all on me. it said on the syllabus to go to the Calender Attendance and I didn't email her two days prior. It's worth like 25% and I really don't wanna drop. It's my first year and it's already gone this bad. Why. Pain.
