I'm a 19 year old male. A couple of weeks ago I had unprotected sex, but not for very long. I do not know if she was HIV positive (I doubt it). A few days ago unusual things that don't normally happen to me have been happening to my body.

- I've been a lot colder than normal.
- It's really hard to sleep (last night & the night before I slept for an hour maybe?).
- I have the flu, which as of now is a runny nose, a little bit of coughing, basic stuff.
- Loss of appetite
- Small headaches
- Little energy/motivation

The weirdest thing though is that whenever I look as far right, left, up, or down as I possibly can without moving my head (or just rolling my eyes) it hurts. I feel a slight pain around the back of both my eyes. This has never happened before. I've checked some other sources online and a lot of these symptoms are symptoms of AIDS, except for this weird eye problem. I've been doing a lot of study for school and I've been looking at a pretty large monitor to study these notes, so maybe that could account for this eye thing.
I have no idea if I have AIDS or not, maybe I'm just freaking myself out and I probably just have the flu. I know the best way to find out is obviously get tested, but I want to see your opinions first. This really sucks, a lot.

Any help is appreciated.
Thanks.
