So I was out for drinks with this girl, and it went all smootly. But all of the sudden she had to sneeze. She did it only one time, apologised, and I told her gesundheit.

But I can't help myself to fabricate scenarios where she did this with ulterior motives, while I'm overthinking inside my head. Like she want's me to react to that on purpose and make judgements about me. The absolute fright of getting rejected homing in on me and I'm helpless to do anything about it while my lack of value will get confirmed once more, like how my mom would completely ignore me when she was on the phone all the time when I was a child, asking her for attention.

Has anything like this ever happened to anyone else? How would you react?
