Hiv test related. Or a dermatologist?

Hey doctor my 4th gen test after 3 month is non reactive and rapid test is negative after 150 and 185 days .and western blot from srl diagnostic after 100 days was also negative .are my results conclusive? Because I am having a lot of hiv symptoms since exposure like infection in mouth and skin plus acnes insomnia and rashes and now scabies . which are not responding to treatment .Doctor said hiv is conclusive and these problem are not related to it.But I am getting very anxious and not sleeping 2-3 days continuously at night . Can you please give suggestion to consult whether hiv specialist or a psychiatrist or a dermatologist?I am being to worried as I read in internet cases where reports where negative for 4 years but hiv was there.Please give any suggestion , I will surely connect back as I wanted to get out of this now it has been more than 6 months now living in constant fear.
