Your previous thread mentioned you were waiting for results and the advice was that test would prove your status.
You have now tested conclusively negative 2 months after your exposure. There is nothing else in your post that is relevant to your negative HIV status, since symptoms aren't used to diagnose.
If you feel that you have a sickness that needs medical attention you should see your doctor because it has nothing to do with HIV.
It is natural to feel mentally horrible if you spend months of terror under the premise that you are dying.
Everyone posts about their self-diagnosed ARS here, but none in my time have actually had ARS, so try to accept that and relax and move on from self-diagnosis.
