Uuuuuh verte I can relate to that... I am always feeling so shit when I am ill..
Last time was especially stupid. I went out on the balcony n the middle of the night just with a shirt, and this in October (I think this might have been the reason).
However, its just a week I am ok again, because I had angina - when I swallowed it hurt, when I ate a bite, it hurt, ...waaah! - then the virus gladly switched to my larynx, and later on I didn´t eat when taking antibiotics, so 5 days of adverse reactions just were the right thing to finish it off.
So, now I´m feeling better, and I can feel for you! Go to the doctor a.s.a.p.! Take what it needs. Stay in bed. You shall rise from there like the immortal eagle.
