Awful flu has me skipping class this entire week

I was sitting next to someone sick and contracted a bad flu, i literally can’t talk or even sit up. I emailed my professors and TAs but I’m lowkey so anxious that they won’t excuse my absences. I know I don’t want to get others sick the same way I did so i’m stay locked away in my room. Has this happened to anyone else and they were ok after one week?
