Madison

I haven't been to school in 2 weeks due to health problems and I'm not aure what to do because homecoming is coming up and I don't want to miss it becuase I'm a freshman and all my friends are going but I don't want to buy a dress and not be able to go. I'm so torn on what to do becuase i want to go so bad but I don't want to buy a dress and be sick. What should I do. This is stressing me out so bad
