Just tested positive for HIV

I’ve avoided getting tested for a long time. As I was afraid of the results. After being with a partner, who contracted syphilis probably from my past before meeting him. I recently got tested and the results came back that I am positive for HIV, and Syphilis, she was very sympathetic towards me and encouraging but I’m still in shock, I feel sorry for myself and I hate that feeling cause I typically self sabotage, I finally got around to being open about my sexuality and now this diagnosis is going to challenge me mentally in many ways. She mentioned that a false positive is possible because of the syphilis and requires further testing, but for now I have to treat it as a positive. And when she asked me if I had anyone in my personal life I can tell, I told her no and it broke me.
