SICK!! And I hate it!

I have flu...to be specific I have swine flu. I caught it from my sister who caught it from her co-worker at the salon, who caught it from their manager. The owner has shut down the salon and put the manager (who knew she was sick but came in anyway) on indefinite leave.  I feel awful. My body aches, my head really hurts, I feel dizzy when I stand up, my stomach is always rolling. I have the worst diarrhoea and keep having to run to the loo. My ear is throbbing and my throat is raw from all the coughing. At least the vomitting was short lived and my fever broke on Thursday, though it's back again today .  The thing is I can't afford to miss more school. I spent the last half hour of my midterm on Tuesday throwing up and I couldn't concentrate for the headache. I didn't do the class participation though I did email the professor about turning it in late (which I haven't done yet). I missed Brit Lit on Wednesday though again I emailed the professor. I'm worried because of my earlier absences I'm just going to fail everything. My doctor (who isn't my usual GP-I had to go to the main hopsital instead of my usual clinic because there were no emergency appointments available on Wednesday except for in the main hospital) told me I was cleared to return to work/school 24 hours after my fever broke. But it's back again today so does that mean I'm still infectious? Should I not go to class this week and risk being even more behind? I can even do my reading because my eyes hurt. I've read a few bits here on DS in the last couple of days because I'm crawling up the walls, but even then I'm left with a massive headache after.  I don't know what to do, and the professionals around here are so not accessible.  And I'm frustrated because though I'm sick. My sister is not disturbed is waited on, but no one seems to have any consideration for me. I'm still expected to cook, and clean up after everyone else, and drive them around when really all I want is to curl up in bed with my tea and sleep for a week. I've been really lethargic and my whole body just aches. But oh well, my sister's boyfriend needs to go to work so up I get to take him in.  After the repo thing he did buy himself a car and I thought I'd have a reprieve. No such luck. Idiot bought an $800 clunker (looks nice but it's a piece of @*&#) and the transmission went out on the 2nd day so now it's in the shop and who knows when he'll get it back.  I'm just so tired and I want to be better again.
