I have a flu and i really don't know what to do.

Fluids: Treatment for the "flu" is for the most part symptomatic as well as common sense. Tylenol (acetaminophen) or advil for aches and fever. Drinking lots of fluid to prevent dehydration. Antihistamines and or decongestants if sinus congestion.

Flu relief: If you have the flu hydrate well w water, herbal teas, soup or juice. Drink sufficiently to have pale to light yellow urine. You can use pain relievers like tylenol (acetaminophen) or nsaid’s. Rest a lot! in some situations antiviral medications (tamiflu, relenza, flumadine) may be prescribed within the first couple of days of symptoms to hasten healing or they can be used after flu exposure to prevent illness.
