Flu... Swine flu... Help?

Ok on Friday I got a tingle in my throat and the Saturday I felt dizzy and slightly rough... Since Sunday I have been in my bed! To begin with I was dizzy, sore throat, ear aches,fever headache, muscle ache, cough bunged up... And feel sick everytime I try eat something! Today my throat is killing me and I'm exhuasted and still feel sick... As u all no it's Christmas in 4 days i need to be better! Anyone got any tips or anything on getting better fast! And how long does it normally last??
