Why do I have to be sick every weekend?

This past week and a half I have been sick with the flu. On Saturday I was taken to the hospital because I got severely dehydrated by the flu. With that I had four iv in each arm pumping fluids into my body. They kept me over night and didn't get home till Sunday night. I have never been this sick so I was really freaked out at first. The iv hurt really bad when they put them in and then the nurse will snotty to my parents which made everyone really testy. Then Jesse came down but he couldn't come into my room because he was sick and with me on iv and having a low immune system with me being dehydrated he couldn't see me, but he did tell me he slept in the waiting room Saturday night and when I got released Sunday night he was waiting for me which made me happy. I just hope I don't have to go through this again this year cause this had to have been the worst weekend I have ever had.
