Saluting with misty eyes
Believe it or not, it is easier than you might realize... once you have gotten over the shock. For that matter, if YOU are this shocked, imagine what your friend is going through.
The last 3 years we were doing foster care, we had 5 kids that had HIV. We were required to do an extensive amount of research and study into HIV and AIDS (different conditions, believe it or not) and the ONE thing that I got out of it was that the kids were normal, mostly-healthy, basic kids that had this disease.
Do yourself and your friend a few favors:
1) Take a Red Cross HIV/AIDS course. They have the latest, most accurate information about the disease.
2) Talk to your friend about it. His/Her doctor will have given her the most accurate, up-to-date information. Besides that, having someone to listen would be a huge help for your friend.
3) Don't treat your friend any differently than you did before you found out. If you gave him/her hugs on occasion, then continue to do so. It is flat out impossible to transmit the virus through hugs. Play, hang out, see movies, whatever you did BEFORE the diagnosis, you can do now. There will be enough people treating your friend differently... don't be one of them.
4) (Obvious one) NEVER, NEVER, NEVER (ad infinitum) do anything to mix any bodily fluids. While the chance of contracting the virus through casual, minor contact is very small... there is still a chance.
Again, learn what you can, and continue to treat your friend as your friend, and not your friend with HIV.
