Symptoms of something serious?!

I've been dealing with mental and physical tiredness, for about 3 weeks now. I'm always tired, always want to lay down, but I'm not nessisarily sleeply. I'm always dealing with headaches in the back of my head, down to my neck. I have a sore throat every morning, that usually goes away by 10 or 11 in the morning, and I also deal with an itch in my throat, that causes it to feel like it's closing up, and I can't breath. And the last week or so, I haven't had hardly any appetite. I usually eat lunch, and a snack and that's it. It's not that I want to starve myself, but the thought of food makes my stomach do butterflies. The last two days my stomach has been completely off, and I feel like I'm gonna throw up every now and again, but I haven't yet.Does this sound like a virus, or something.? Or just a common cold.? I've looked at different things, I know mono has started going around my choir, but my symptoms didn't really match. Any help would be greatly appreciated.Health Question & Answer
