I'm so sorry to hear that. I'm just out of a relationship where we had unprotected sex and my boyfriend lied to me about his previous sexual contacts, so I'm at the moment waiting for the results of the battery of tests including HIV I had done this week. I cannot imagine how I'd feel if my test came back positive! Try and talk to people who live with the virus and as has been said already, things have moved on since the 80s when it was a death sentence. Enjoy life and consider the retroviral treatment the same way you'd consider insulin if you were diabetic, or inhalers if you had asthma, i.e. I have an illness, tough, this is the treatment and I will get on with life despite it.
Hope some of our messages make you feel a bit better.
