Can you write me a script for steriods?

Just kidding.
I need some free medical advice. I think I may have the flu or something. I very rarely get sick (I cant remember the last time), so this isn't "old hat" for me, even though it's likely no big deal.
I got up this morning and felt fine. Around 9:00am I developed a dry, intermittent, painful cough. By 11:00 it had gotten worse, and I got a splitting headache and muscle aches. By 12 noon I started feeling weak and shitty. I went downhill from there, and by 5:00 I was feeling terrible, with all the above symptoms plus feeling hot and having heart palpitations. I finally ate something around 6 had no appetite, and took my temp... it was 99.6. I was also cold, and jacked my house temp up to 76. I took my temp again at 10:00 and it was 101.8. I feel really shitty,and took 400mg ibuprofen @ 10:05.
Do I need to go to the doctor tomorrow, or can I just wait this thing out?
Yeah, I know... "meltdown".
