Hi and welcome to the infectious disease forum. We are not doctors on here but I am a microbiologist and can give you some suggestions. Since you are negative for a lot of things. I wonder if you should retest for Eptein Barr Virus or EBV. It can sometimes come back have a recurrence of symptoms. Most people are exposed to it by adulthood. But some strains or some people's immunity varies so you could see if you have a relapse. Get the one with Early antigen, Nuclear antigen, etc. not the mono spot test.
Has your thyroid been tested? That can become hypothyroid as a adult even when you have been normal before. It makes you very fatigued. So getting your TSH value would help too.
Any weight loss or pain, fever cough or anything other than fatigue? Any recent travel?
Sorry I meant Epstein Barr Virus.
generally i look very healthy i visited a lot of doctors they talk about psychosomatization disorder which probably would be the right diagnosis i think so i am starting CBT and anti anxiety medications ....
If the CBC was normal that is a great sign of no lowered immunity for HIV. The lymphocytes would be very low. If you are worried Get an HIV test especially the HIV duo test with PCR and serology. If it has been 28 days or longer you will see the serology results. If it is < 10 days I would wait to test about 28 days after exposure.
