Sir. Recently .I was asked by my neighbour to Repair the waterpipe which is buried underground. I went and started to dig for buried pipe. As approaching the pvc pipe. The pipe is covered by clothes. To cut the clothes I asked scissors. And he take one scissors and gave it to me. I started to cut the clothes. Accidentally scissors injured my left thumb and 6 drops of blood came. And I asked ,where he brought the scissors and he said he took it ftom a tailor. But the Tailor is a HIV positive person. I'm caught with fear &anxiety about infection of HIV to me. Another situation also happened same neighbour took me to give electric connections to motor in his farm. I went there and started to make connections .then a person came to us and joined making connections along with me. And he twisted the copper leads of the wires and gave it to me. Then while plastering the twisted connections made by him one pair of wires connected are separated then I twisted them with my hand. Then the copper leads slightly penetrated into my fingers. The previous twisted person having hiv infection. Again I'm caught with the same fear. Again recently I was taking badam milk from a cool drink vendor who himself makes cooldrinks. While drinking it accidentally my tongue was bitten by me and it was bleed while drinking. And I'm getting thoughts if the vendor is having HIV . I also have the possibility to have the infection . I'm obsessed. I'm fully scared. Kindly help me whether I have probability to have infection if no why. If yes how to I diagnosed. kindly help me with my worry.
