Every possible symptom. Psychosomatic?

I have foul smelly soft stools with indigestion, loss of appetite, tiredness, weight loss, shortness of breath for the last two months,vision problem,hands and body shakes when i stretch, forgetfullness, loss of libido. When i wake up , i feel like nauseous and something is in my chest.  I saw two doctors till date but problems have not yet been solved.  I told them i could have hiv, i got tested using tridot and western blot,  both negative. My exposure was 8 years back .  Are my symptoms psychosomatic? Because i have always feared hiv since my exposure which was 8 years back.  Not hiv alone, when i was young(7 to 10 years old)  i thought id get crazy, and i was always panic stricken asking people if id go mad. The two doctors who told me im hiv negative also ran other tests. They told im healthy but i keep experiencing these symptoms. Im still worried it could be hiv because in some patients in late stage hiv , antibody tests wont detect hiv. What shosho
