I've been to the doctor and even the ER to address the symptoms I'm experiencing, which continue to change every day, and it's still unclear what's going on with my health, but it apparently has nothing to do with HIV.
I tested negative twice with 4th gen quantitative tests for HIV-1, and negative at 5.5 weeks with Oraquick (HIV-1/2). (This leaves only the slightest chance that I might have contracted HIV-2 and had a false negative with Oraquick, but I don't take this possibility very seriously, and I expect to get a negative at 12 weeks with a standard 3rd gen qualitative test.)
The moral of the story is, believe the moderators when they tell you your symptoms are not specific to HIV. I could not have been more convinced that I was positive, for a period of over a month. In that time, when I thought there was almost no reason to doubt my upcoming diagnosis, I was busy preparing myself for a new life (although what it would have actually been I have no idea). From my experience I would recommend 1) NOT using a private STD testing service without the involvement of a doctor, you won't believe the results when you get them if they're not what you're expecting, as I didn't for over a week of prolonged agony 2) NOT convincing yourself that you either have HIV or don't have HIV. The second point is especially hard, but it's not difficult to see that it won't make a real difference once you have your actual test results. It's just a way of dealing with your anxiety. In the end, just be glad you know you've had a risk and you know when to get tested.
I don't feel any joy or even much relief over my negative result, and I don't want to tell people "Don't worry, I'm sure you'll be fine! Like I was!" It seems irresponsible to promise that, and I'm still to some extent in the mindset that, unlike the rest of the population, I have HIV, and I still read the forums daily, I'm still in awe of people who have been living with this for as long as 30+ years, and I know there are countless other people who have the disease now and will contract it in the future.
