I am a 29 year old male from Mumbai working in an MNC. I am getting married on Feb 7th 2017 and below is my detailed health concern. I am a sexually active person in my life I had taken a big risk when I had brief unprotected sex with a CSW on 1st October 2015 (Post which I have never ever visited any CSW or taken any such risks) The act made so scared that I got myself test with 4th generation test at Metropolis India after 7 weeks of exposure. Reports were negative initially I was very happy but slowly many doubts raised in my mind because of excessive research online and so I got myself tested again and again. In this one year I got myself tested 15 times. Just when I was about to forget things and live a normal life my fiance gave me a shocking news that in Sep 2016 she had sex with her childhood friend once. She was guilty about and asked pardon for the same and I also forgave her. But yet I made her take the test after her three weeks of sex and I also took a test. Post which we had sex on 1st Oct 2016 and again for reassurance I took a test 4 weeks later. Now my worry is: 1) The chances of her getting infected from her friend for a very brief sex is very low but still I doubt her and the situation despite the reports coming normal. technically I risked myself by going to CSW but she did not do anything of that sort but I still doubt I do not know why 2) Recently I got a small cut from a barber shop and than again I started getting paranoid about HIV. 3) Time and again and again for every small thing happening to me i.e. Cold, cough I relate it to HIV. My day starts with the thought and hear of HIV and ends with it. I am unable to cope up with these thoughts and behavior towards it. I know life is very uncertain but yet I keep thinking about and getting tensed a lot. Please help me with all my worries and anxiety, help me out with detailed explanation.
