I am very sorry to hear about your ordeal. Rape leaves one so shuttered and scattered. Happened to me at least four times in Kenya. And I fought off three attempted rape monsters.
You have a voice because you are already talking about it. It is one way to heal. I told a friend when I was 17 years old about the rapes that had occured and never spoke about it again until I was 30 years old as I gathered that even Oprah was raped. She gave me my voice and no I don't watch Oprah anymore.
If you want to confirm your results, you can do a western blot test. Also, get yourself checked for other STDs. So sorry.
What you went through 7 months ago is traumatic to say the least and will take your body a while to get back to normal. Or at least to feel as though you are back to normal.
This sounds like you have no HIV in your blood.
Take heart
