Welcome to the forum.
You had accurate replies (a few times) on the community forum. You had an exposure that was essentially zero risk for HIV and didbn't need testing -- and you certainly have been over tested given all the tests you had. In any case, your results prove you were not infected. Test results always overrule symptoms and exposure history, and your results show your symptoms are not possibly due to HIV -- and they aren't suggestive of HIV anyway.
There is no additional testing you should or could do to "bring closure". The ones you had, in combination, prove with 100% certainty you don't have HIV. Don't ask for further clarifications about it; there are no extenuating circumstances you can think up that would possibly change my opinion or advice, so I won't have any further comments.
