I have a horrible headache
Bad cough, runny nose
I feel very weak and light headed
When I stand up I get this hazy feeling
If it helps I also have a rare disorder known as Kostmann's Syndrome. I didn't really eat much today except breakfast.

And please no smart comments.

Your symptoms don't sound out of the ordinary. I'm not a doctor (I don't even play one on TV), but it sounds like you've got a really bad cold or the flu.

Try to eat some soup that's not heavy (tomato, chicken broth) or drink some juice, just to get some fluid in your body. It will probably help with the dizziness.

You have a flu virus.

use Tylenol once a day so your headache bad cough,running nose it will go away thrust me used tylenol

I cannot diagnose, only a doctor can formally diagnose an illness.
It sounds like you have flu. You really ought to eat something small if you can but it is more important you get as much fluids as possible.

EDIT EDIT EDIT

Kostmann's Syndrome means you lack neutrophils and so get infections more easily and they are harder to get rid of. Go see a doctor, left untreated your symptoms may become dangerous.

If you are truely concerned you need to see a doctor. It sounds to me like a flu. Take a tylenol for the pain and go back to bed. Drink lots. plan on feeling like crap for a week or two.

Since you may be prone to infections, it would be good to see your doctor to be sure it does not become something more severe.

you may be coming down with a cold. you should eat though. i get bad headaches and feel light headed when i dont eat.
