My attendance is at 81% and I only missed about 16 hours of lessons

Kinda embarrassing, but my attendance is very low, and while it was mostly because of some horrid flu or even covid right now, I haven't been doing well mentally, I can't physically step into school due to anxiety, and then if I do miss school, I also get anxiety. I don't know how to explain it, but is it possible that universities will not like that my attendance is so low? I also don't get how it is so low since I only missed about 5 days due to sickness. I'm just so worried if I don't go in tomorrow, I will get some crazy, unnecessary meeting, which won't help at all. Nothing makes me want to go to college, and thats what makes me feel bad.
