All I can think about is having terrible colds, so bad I can't get out of bed from it.
But I remember a time I once had a migraine, and I had the worst headache and was in bed all day sweating and being sick because it was that bad.
Right before I turned 2, I was hospitalized for about 4 days. I was home sick for a few days before that, with a 105 fever at the worst of it. I was vomiting nearly every hour and so dehydrated I passed out. An ambulance had to come! My mom, dad, grandma, grandpa, and Uncle Jordan when he was A LOT younger all took turns staying with me in the hospital. I had to get an IV, it was that bad. On the bright side, we met my doctor who I've had ever since!
I got food poisoning once and was sick for a week and a half. It was so horrible, I prayed I was able to go to school, even on Monday! I still felt bad when I did, but the worst had passed and something fun came out of it:
M brother told everyone I had the 'Black Plague' and I just said 'Yeah! But, I'm better now~ :3'
The sickest I've ever been would have to be from kindergarten through fourth grade when I constantly had stomach flu once every year and a cold every two weeks. Despite my mother's care for me, I was a sick baby! However, more recently last year during my junior year in high school, I had the worst case of the flu. Weakness accompanied by dizziness and "thunderclap headaches", as well as a cough and stuffy nose. It was awful. Glad you're recovering!
I hope you feel much better soon. Glad your feeling better.
The sickest I can remember being was when I had the flu at age 7 or 8, and is sadly one of my earliest memories. I remember being on the couch with our three heaviest blankets on me, freezing cold. Everyone else was super hot, but I was cold and sweaty. Not fun. :P
