You had no risk. Nothing you posted has anything at all to do with HIV.
Some underlying emotion, may be guilt of cheating or perhaps fear of infection leading to stigma and a lot of justification could be some of the reason in your case. Mine's just a guess, you need to work with a counselor for fact-finding or rearrangement of thoughts since nothing points towards HIV.
What ever your discomforts are, mostly it is suggesting to be classic anxiety symptoms. It is no relation to HIV, because you didn't have a risk to begin with. You must be checking your body every now and then. You surely have no moment thinking and grieving about HIV. Your fears are irrational, seek help for the real problem, this forum is specific to HIV, your answers are not here. You don't have HIV.
