“I had two high-risk encounters a month ago. Then a friend joked, ‘Aren’t you scared of HIV?’ Since then, I’ve been terrified of HIV and haven’t slept well for two weeks. I bought three home test kits, tested once, and it was negative. But the seller said I’m still in the window period. I’m too scared to go to a hospital—I’m afraid people will find out, afraid of judgmental looks, and I can’t bear the thought of a positive result… What should I do?”
