Medical Help

Alright, I know there's probably 0 doctors running around here but I figure the community is at least getting a little older and maybe someone has had the same thing happen to them. I've checked my symptoms with one of those online diagnosis things and they've all basically told me to call 911 or get to an emergency room asap. But I don't believe it's near that bad yet.. Here's what's going on:

Fatigue - I basically don't want to move at all

Weakness - I had no problem benching 170 a few weeks ago and now I have trouble getting 135 up

Irritability - Everything is pissing me off, even the stupidest little things

Headaches - Off and on, they come on hard and go away pretty quick

Increased appetite - I want to eat all the time, no joke

Stomache pains - If I don't eat I feel sick or like I'm going to pass out. When I eat I feel like I'm going to vomit for an hour or so

Bruising - Honestly, I've never bruised this easily before. I messed up my ankle just messing around a few days ago when I usually would have just twisted it and been fine within a few minutes.. I've been down for 4 days now.

Originally it started with just the fatigue. I had stopped drinking soda so I figured it was just the lack of caffine but I started drinking soda again and the caffine doesn't help. Then the irritibility I blamed on the fact that the girl I was head of heels for decided she wanted to move on but that was weeks ago. And now I don't have anything to blame the rest on so something has to be wrong. Anyone got any ideas? I'm just praying I won't have to have another visit to the doc. He already thinks I'm an idiot for messing up my ankle like I did..
