Hello
Your female friend is right , if any thing were wrong with her, that would would have shown in blood tests i.e. she is HIV free .
She is also a
skin cancer patient , so her immunity is also low , this means if she would have been a patient of HIV that would have shown .
In my opinion you don't require any blood test as you are HIV free , not a cause of concern .
As you mentioned that you are were a patient of OCD and anxiety , so that is the reason that you are over conscious about HIV infection .
So enjoy life and remain tension free.These are early signs of HIV :
Fever,
pharyngitis, headache/retro-orbital pain ,
lymphadenopathy, arthralgias/myalgias , lethargy/myalgias, anorexia/
weight loss, nausea/diarrhea/vomiting.
Erythematous
maculopapular rash, mucocutaneous ulceration ( tongue and in mouth).
