Dear Doctor, I am 26yrs old male. I have certain mental pressure. I had a sexual contact with unknown person from that moment my thought changed. i myself thinking whether i had got HIV. So i took a HIV test for more than 10 times in the window period and after the window period all are negative. I cant able to forget that incident and also i am now thinking HIV will cause by syrengi so am more afraid due to i injected blood for more than 10 times for checking HIV. My problem is i am getting more tired everyday and cannot do any work with fulfillment. Kindly help me.
