worst night's sleep ever

I don't think I have ever slept that badly. that was really awful.I swung between syupidly cold, to crazy feverish hot. I dehydrated so much that I almost passed out trying to get to the bathroom so I could take some more painkillers.My ears feel like they're about to implode and my back is killing me.As are my legs, head and sinuses.this is really horrible.I called in sick to work, can't concentrate on anything long enough to get work done.No one's home and my parents have gone away for the weekend, so I can't even mooch off them.I'd go to the doctors, but I'm a bit worried I'll pass out on the way.I hate this.
