Hey man, according to the CDC guidelines, median progression period between HIV infection and the onset of AIDS is 8-10 years. Now, that does not mean that one day after 10 years you are perfectly and the next you are dying...the majority of people start getting ill as their immune system goes down (CD4 cells dying), so when your CD4 count gets to below 200, regardless of whether you are sick or not, your status is defined as AIDS.
It takes 3 months (for most people, 6 for all) to have HIV antibodies detected in the blood. You tested 3 times after 10 years, that means you are negative at a 100%. Some people say that antiretroviral therapy canmake some positive people show negative at the late stages of infection. I dont think you have been in HAART so, again you are not infected.
About your symptoms, there are many things that can cause them, but it is certainly not HIV. May be a reactivation of Epstein/Barr (mono, cebv)or some other virus. Anxiety is a BIG factor, and for some of us that are just starting with symptoms after a few months of exposure, I can tell you is a hell of a time. So you have had a long, long time to wait and you are negative! keep it that way, calm down, and try to tackle your symptoms from other perspectives.
Live well!
