What sort of symptoms are you having?
You are not likely to die if you don't see a doctor, however there are alot of different flu strains out there, and some can be fatal. If you do not see a doctor, expect to feel worse than hell on wheels for about a week. I think you should see a doctor. - Blu
If you think you have the flu, you must seek medical attention. It's nothing to mess around with.
Hope you feel better soon.
